Easiest way is to compile it under cygwin, and have it run in the Cygwin X server. If you port it to a cross-platform GUI toolkit like QT, then you can compile it natively for each platform. (Or maybe with mingw or even still cygwin on windows, if it does much besides being a GUI and needs POSIX library functions and system calls.).
In the latter case, your first bet would be to compile under Cygwin and see what errors and library it finds missing and try to install them in your Cygwin installation. You can proceed incrementally this way.
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.
