Gui in C on windows cygwin

I'm trying to make a script that can generate a kind of chat client in cygwin on windows but I don't have a clue how to start, I saw something like gtk+ b开发者_如何学编程ut how do I get that inside of cygwin, and what have I to do after that?

Cygwin has an assortment of gtk packages. After that you need to read some documentation and learn how to use the toolkit to make your program. Here is a tutorial to get you started.

Are you locked to Cygwin or are you using that because you think that is where Gtk+ apps can run? In any case I seem to remember those packages as options in the cygwin installer. Also this link seems valid: http://sourceware.org/cygwinports/ . I tend to generate native programs using Gtk+ on MinGW instead so my users don't have to have all of cygwin installed to run my software.
