You can't developer iPhone app on windows in the for the native SDk (read Objective-C) you can use HTML apps and developer them on windows. Or use MonoTOuch (which will need to build the app on a mac).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
