Hmmm,
    I dont think this should be in the gtk+ domain.
Why not just use a GtkEntry and use string conversion utilities
(i.e. isdigit() or some varient) ?

You can preemptivly deny some charachters input by catching
the GdkEventKey's (i.e. "key-press-event" on the GtkWidget object)
in advance and returning TRUE if you dont want that key to be
processed (i.e. if you dont want the GtkEntry's handler to be called).
