iPhone Apps development SDK used is called XCode. In XCode we use different types of frameworks for e.g. Cocoa Touch , UIKit Framework, Cocos2d and Cocos3d etx
This site tells you pretty much everything that you need to know to get an iPhone app, launch it and how to be successful in doing so, and also the suggested eBook is great which I have used: How to make an iPhone app (even if you don't want to make it yourself, how to hire someone to make an iphone app).
iPhone application development is based on ajax world.There is lots of tutorias regarding the application development and the complete detail regarding softwares also.The latest iPhone software OS 4 SDK (Software Development Kit) allows the iPhone developers to customize software so that end users can easily run wide ranging mobile apps on their mobile device.
Best option is to use SDK, but it might be better to pay someone than to try to code something yourself.
The language used is called "Objective-C" and it's on the Cocoa Framework... Buy an Apple machine with an intel processor and then download "Xcode"
