In the Nov-Dec 93 issue of The X Journal, J. Darren Jones suggested an alternative approach to the 2 functions per callback mechanism (D Young's method).

The article proposes a Callback class that acts as the interpreter between the GUI components and the Intrinsics.  Such a class provides the protocol the GUI developer wants and the protocol expected by Xt.  An implementation is also provided.

I can not vouch for the suitability of Mr Jones's approach, but it is a very interesting article.
