glade-gnome 2.12.1-1ubuntu4 (amd64 binary) in ubuntu dapper

 Glade is a RAD tool to enable quick and easy development of user
 interfaces for the GTK+ 2 toolkit and the GNOME 2 desktop environment.
 It also contains built-in support for generating the C source code
 needed to recreate the interfaces.
 .
 The user interfaces designed in Glade are stored in the well-known XML
 format, enabling easy integration with external tools. Several tools are
 already available which can turn the XML files into source code in other
 languages such as C++, Perl and Python. Other tools such as libglade can
 load the XML files and create the interfaces at runtime.
