Yes, The following should work:

{
   XSetWindowAttributes att;
   XtValueMask mask; /* or unsigned long */
   Widget bp; /* push button widget */

   .....
   pb = XmCreatePushButton(....

   mask = 0;
   mask |= CWBackPixel;
   att.background_pixmap = ParentRelative; /* this is the solution */
   XChangeWindowAttributes(XtDisplay(pb), XtWindow(pb),
                           mask, &att);

   .....
}
