Where can I use it?
Everywhere! GTK is cross-platform and boasts an easy to use API, speeding up your development time. Take a look at the screenshots to see a number of platforms GTK will run.
What languages are supported?
GTK is written in C but has been designed from the ground up to support a wide range of languages, not only C/C++. Using GTK from languages such as Perl and Python (especially in combination with the Glade GUI builder) provides an effective method of rapid application development.
Are there any licensing restrictions?
GTK is free software and part of the GNU Project. However, the licensing terms for GTK, the GNU LGPL, allow it to be used by all developers, including those developing proprietary software, without any license fees or royalties.
