How to write a cross-platform program?

Question

Greetings,

I want to write a small cross-platform utility program with GUI in it. What language/GUI-library should I stick to? Is it possible whatsoever?

Answer 1

If you know C or C++ the first cross platform GUI framework I can think of are:

• QT (C++, proprietary but free with the LGPL licensing)
• wxWidgets (C++, the most complete and stable but also huge)
• FLTK (C++)
• FOX (C++)
• IUP (C, simpler and cleaner than the ones above)

If you know Pascal, you can try freepascal+Lazarus. I've never used it, though.
