This is already implemented in the 1.3 developer tree. From the Changelog :

Sun Feb 28 16:46:02 1999  Stefan Jeske  <stefan@gtk.org>

        * gtk/gtkspinbutton.[c,h] gtk/testgtk.c: Added two new signals to 
        GtkSpinButton, "input" and "output", to make the output more flexible.
        The user has to provide a mapping between adjustment->value and the
        output string (and vice versa, if the spin button is editable). 
        See testgtk for examples.

This might fit your needs. Just have a look at the testgtk sample.

bye,
   Stefan
