Editor application with grid

[Dieter Schicker <dieter schicker uni-graz at>]

Hi,

I'm planning to implement an editor application where I want to give
users the ability to drag together different types of widgets on a grid.
I wanted to do it in Java, but now after some weeks of experience with
gtk perl I would really like to implement it with Gtk. 

Has anybody done something similar already? Any hints?

Many thanks in advance
