software with a GUI but can also be used for non-GUI applications.

Gtk

PyGTK provides Python bindings for the GTK+ toolkit. Like the GTK+ library

itself, it is currently licensed under the GNU LGPL. It is worth noting that

PyGTK only currenty supports the Gtk-2.X API (NOT Gtk-3.0). It is currently

recommended that PyGTK is not used for new projects and existing applications

be ported from PyGTK to PyGObject.

Tk

Tkinter is a thin object-oriented layer on top of Tcl/Tk. It has the advantage

of being included with the Python standard library, making it the most

convenient and compatible toolkit to program with.
