I've tried almost all GUI libs available on Libraries page. ParaGUI is
feature-complete but heavy and seems to be dead.
aedGUI promised to be good library but now seems to be dead too.
Recently I discovered SDLtk - and liked it. I don't see it developed,
author only recently uploaded it to SourceForge, so I hope it will be
developed.
Agar is also interesting. Other libraries are quite old and incomplete.
