Original Post
I''d like to create a super basic GUI --- that could compile and run on any platform. Right now, all I want is a message box or something. I want to create a windowing library that I can use in my projects that will run under Linux or Windows or Mac, etc. Language independent -- no particulars necessarily. I just would like to know some theory on creating a messagebox library that could run under any OS -- in theory. How do things like WindowsMX work?
Thanks.
