Programming Languages for writing GUI application [closed]

Question

Other than .NET or Java, which language can be used to write an application for Windows and Linux?

Answer 1

You could reverse your question : what toolkits are there, and which languauges do they support?

For Example GTK : (from wikipedia)

C           GTK+ 
C++         gtkmm 
Ruby        ruby-gtk2 
Python      PyGTK 
Java        java-gnome 
.NET        Gtk# 
PHP         PHP-GTK 
Perl        Gtk2-Perl

You can find support for many languages if you explore these other widget toolkits :

FOX toolkit — A fast, open source, cross-platform widget toolkit
GTK+ — The GIMP toolkit, a widget toolkit used by GNOME applications
