Marbles is the pygtk GUI builder tool for pygtk almost like glade, but would be optimized for sugar environment.

#:'''Python''' Python is powerful,easy and fun. It is an excellent choice both for development and usages for children,students as well for professionals for writing complex applications. if GUI builder is to be compared with RAD, I would say R(Rapid) in RAD stands for python.

The python bindings (PyGTK) of this toolkit are elegant and both GTK+ and PYGTK have excellent documentation.

Where input is a UI canvas which shows widgets with its correct alignment. Processing is the program generator which takes the information of widgets from the canvas and output is a code generated from program generated ( Python, C/C++ or XRC source )
