Answer to Question One:  Yes, there are bindings available.  The
STARS repository should have a copy of the Boeing bindings.  At 
AFIT we are using a commercial set of bindings that give full
X lib, Xt and Motif functionality.  The company that markets this set
of bindings is Systems Engineering Research Corporation.  The product
is called Ada/Motif.  There are other public domain and commercial
binding sets available beyond these.

Answer to Question Two:  Callbacks are registered by supplying the
address of the function.  

    Xt_Add_Callback( Target_Widget, Xm_N_activate_Callback,
		     Callback_Function'ADDRESS, Data'ADDRESS);

Note that the 'ADDRESS attribute does supply a pointer to the function.
