Compiling a GTK+ application for windows from linux

I'm new to linux and have been learning gtk+ the past couple of days, and was wondering how you would go about compiling an applica开发者_JAVA百科tion to run on windows instead of linux (ubuntu). I found this while doing a quick search but my knowledge of linux is non-existent at the moment so not sure how to proceed with the tutorial. Are there any alternative methods to do this?.

I've only compiled on Windows and used Cygwin to test 'nix versions (before going right into a 'nix OS and compiling), but looks like this might get you started.

Compiling in other OS does not make sense while you can't disribute your binary without testing it on the target platform. Then why not to compile on the same platform?
