Another way of achieving a similar result is to use the 
gtk_object_set_data (or is it gtk_widget_set_data?) which allows you
to associate arbitrary data with a GTK object keyed by a string.
This can be useful if you want to associate some data 
with a widget then pass some other data to the callbacks in the
'data' argument.

The structure method is probably better in this specific case, however.
