Question about developing programs...

[Andrew Konosky]

I have been writing a small program in C++ with KDevelop to calculate 
vectors for physics class, and I have compiled and installed it so that 
it runs when I type the command in the console, which is really cool! If 
I want to cross-compile it to make a windows version to give to some of 
my friends, how would I do that? I'm guessing it would just be a DOS 
file, since there is no gui?
