I would use a gtk.TreeStore() model in a gtk.TreeView() widget.  Using 
the first one or two letters of the name for the tree nodes.

Maybe in a Dialog window if there isn't space for the gtk.TreeView() 
in the GUI.

It is possible use a lazy mode and only populate the gtk.TreeStore() 
as the user clicks on the appropriate nodes.
