Possible iPhone / iPad Development

I've been looking to jump into app development for quite some time now. There are a hand full of applications and game ideas I would like to create and release. However, I'm not willing to purchase an iMac as I'm a Windows user unless it's the only good option.

I did find DragonFireSDK http://www.dragonfiresdk.com/

Would this be a recommended option to begin development? I don't mind purchasing software, so any suggestions are appreciated!
