      GTK+ is a highly usable, feature rich toolkit for creating
      graphical user interfaces which boasts cross platform
      compatibility and an easy to use API.  GTK+ it is written in C,
      but has bindings to many other popular programming languages
      such as C++, Python and C# among others.  GTK+ is licensed
      under the GNU LGPL 2.1 allowing development of both free and
      proprietary software with GTK+ without any license fees or
