Glade is a RAD tool to enable quick & easy development of user
interfaces for the GTK+ toolkit and the GNOME desktop environment.

The user interfaces designed in Glade are saved as XML, and by using
the GtkBuilder GTK+ object these can be loaded by applications
dynamically as needed.

By using GtkBuilder, Glade XML files can be used in numerous programming
languages including C, C++, C#, Vala, Java, Perl, Python,and others.
