Is it possible to simply take a picture and save it somewhere using a QTCaptureView and Apple's built-in iSight? I've seen lots of tutorials on recording video but none on simply taking a picture. Any help or guidance is appreciated!

You can do this with QTKit - the QTKit Application Programming Guide has a section for this titled, "Creating a Single-Frame Grabbing Application".
The better approach, however, is ImageKit's PictureTaker. It gives you the standard UI found in ImageBooth and other apps and is dead-simple to use in code.
I found the source of ImageSnap useful for understanding how to use QTKit to do this sort of thing. It is a simple command line application for taking pictures with the iSight camera.

Origami - the Facebook prototyping tool has some amazing UI effects.
Is there any way to actually use those when I'm building my app?
There's currently no way to include animations from origami into your app.
However...
Facebook announced Pop a few days ago, which is the animation engine they used in their app 'Paper'. You can hear all about it Here. And the good news is Pop integrates with Origami, making what you want possible, Pop will be open source (to be released very soon they said), so keep your eyes open for it.
You can use "Code Export" to export animation code in Origami 2.0.
Origami is for prototyping animations. If you want them to be real you have code them yourself. There is no export to code feature or something like that.
Joris Kuivers has released qc-mobile as mentioned in this blog. It is a starting point.
I saw lots of QuickLook plugins (like BetterZip Quick Look Generator) coming together with their nice and tidy interfaces...I tried to design the GUI of my own one using HTML and JQuery, but I don't think that it's a good solution (plus, on top of that, Xcode 5.1 doesn't allow you anymore to include or open files from other directories with the <src> attribute).
I'll never thank enough Jelle Vandebeeck for opening my mind with his beautiful and helpful post, but unfortunately there's nothing on the internet regarding this topic (I think that there might be something on The Big Nerd Ranch Guide, but it won't be out before October).
So, I was wondering if anybody of you:
OPTION A - Knows the title of a guide that can explain how to develop/create a GUI for my QuickLook plugin in a "didactic" way (like a text book, step-by-step);
OPTION B - Could write down in the answer a couple of code lines to insert a button and a text field with the usual "Hello World!".
I have a sub-question related to the main one: is it possible to keep the semi-transparent white/grey background colour that a QuickLook window (like the one that appears when you select -for example- an audio file) usually has?
Thank you so much in advance!
In terms of a guide, there's the QuickLook Programming Guide over in the documentation. It goes over the architecture of QuickLook and walks you through the various steps of building a QuickLook plugin, including one that returns rich HTML content.
Related to this are a couple of pieces of documentation on how to integrate QuickLook into your own app, but it sounds like you're more interested in the plugin aspect.
Together with an illustrator I want to create some screens with lots of animations/transitions (moving sprites). I need the illustrator to do the animation. He knows how to use AfterEffects so best would be some kind of timeline-tool to create the transitions/scalings/alphas etc.
My question is now: Is there some kind of tool out there that could be used to create animations and then export the used parameters to objective-c to import it to xcode?
Thanx!
To my knowledge: No.
We spend some time a couple of months back trying to find something similar to Expression blend, just for iOS, but without luck.
If you however are planing to make your app for MacOS and not iOS you can take a look at quartz composer. For iOS you could also take a look at storyboard (here is a link to fairly good tutorial), but I'm afraid your needs will not be met by the features of storyboard.
I found Flash2Cocos2D and I think this is the best solution available right now.
Also promissing: cocosbuilder!
I'm not sure of the correct name, but I am wondering how to create (in Objective-C) a transparent notification "window/panel", such as is shown when you change the volume intensity, or keyboard illumination, or display brightness. I want to put my own icon/text on it, for my own notification.
I don't know the words to Google for, so I'm asking here.
Thanks for any suggestions.
Matt Gemmell's RoundedFloatingPanel component on his sample code page may do just what you're looking for.
After looking into using the solutions provided by the other two given answers, I found that they would not work for my purposes. So, I wrote up my own library:
BHBezelNotification
Growl is a widely-used implementation of this. By default, it doesn't look exactly like the system overlays, though it is skinnable - you probably want the Bezel notification:
See the Growl Developer Documentation for more.
I am developing an iPhone application where i want to display three image in each row on scroll view where i need to click action on each image like Photo album in iPhone. I am not getting any sample code.
Hoping for help

There's plenty of sample code out there, I found this after only basic googling. You want to search for "UIImageView Iphone". It's also worth mentioning that Apple's very own Developer Center is extremely well written, and will teach you everything you need to know about iPhone programming.
Generally it is frowned down upon to say to look more or read documentation, but you really haven't looked at all. Especially because of Apple's own resource that tells you how to do almost anything, especially something like this. It's not something you can pick up and bits and pieces of and expect to be successful with, it really should be learned starting from the beginning and moving forward. This is especially true if you've never programmed before or are unfamiliar with C/Objective-C.
Three20 has a photo browser that is open source and works similarly to the iPhone's photo browser with some nice code examples. The images come from an image source object that can relate them to images in your apps bundle or images on the web. Looks like its Google group is here. I think that to use images in your bundle you use a URL formed like: bundle://image-name.png and not the typical use of the main bundle to get a path to resource.
