In R3 there isn't any convenient way to do this, short of the sort of hack that
I described in my previous posting this morning, which would involve doing the
drawing yourself.

In X11R4 there is a routine that has been added to let you call a widget's
action proceedures from an application.  This way you can call the highlight and
unhighlight actions on Command button B from an action routine invoked by
Command button A, provided that you have the widget ID of button B.

No, R4 isn't out yet, we are still looking for release "late this year".
