Windows SDK for COCOA API

I'm just starting off with IOS app dev. I was just curious to know if there are any sdk's in windows available to simulate the cocoa API. In simple words can i program, 开发者_运维百科compile and execute an Objective-C code on windows OS through any simulators, if any?

The original question was about running Cocoa apps on Windows, not developing iOS apps under Windows. There are a few projects that are attempting to implement the Cocoa APIs under windows, but I'm not sure how successful they are being. There is one at http://www.cocotron.org/ which looks promising.

Unfortunately, the only real way to do iOS development is in a genuine Mac environment.
