libgladeui-2-6 binary package in Ubuntu Trusty amd64

 Glade is a RAD tool to enable quick and easy development of user
 interfaces for the GTK+ toolkit.
 .
 Glade is, since its "3.0" major version, highly modular, and composed
 of widgets which can be used by other applications to integrate
 functionality similar to the one provided by the Glade application
 itself.
 .
 This library provides all the widgets and core code, like parsing and
 saving files.
