Recently, I surfed the web looking for multi-platform GUI toolkits, available for GNU/Linux and being ported to Mac OS X/Darwin. I welcome comments from developers more experienced in these respective technologies.
1. the Gnome desktop environment with the Gtk+ toolkit. GPC bindings are available in the gpc contrib directory, but they are based on Gtk 1.2 rather than 2.x. I believe, I saw Gtk 2.x bindings for Free Pascal somewhere on the web, but I may be wrong.
2. the KDE desktop environment with the Qt toolkit, which is C++ based. So, in the Gnome versus KDE war, Gnome seems to be the natural choice. Also, you have to pay for Qt, unless you write GPL licensed software.
3. in the sources of KDevelop, I found references to GNU Pascal. However, KDevelop is not mentioned on the GNU Pascal website.
4. GLUT ...
5. Open Motif ...
6. LessTif ...
7. TkInter ...
8. Perl/Tk ...
9. Tcl/Tk ...
10. WxWindows ...
11. XForms ...
12. Mowitz ...
