Glade is a RAD tool to enable quick and easy development of user
interfaces for the GTK+ toolkit and the GNOME desktop environment,
released under the GNU GPL License. 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++, Vala, Java, Perl, Python, C#, Pike, Ruby,
Haskell, Objective Caml and Scheme.
