I've had success with code like this - it works under KDE and GNOME - I
havn't tested it on any of the others:

-------------------------------------------------------------------------------
   PropMotifWmHints motif_hints ;
   Atom             prop, proptype ;

   /* Set up the property */

   motif_hints.flags = MWM_HINTS_DECORATIONS ;
   motif_hints.decorations = 0 ;   /* NO DECORATIONS */

   /* get the atom for the property */

   prop = XInternAtom ( disp->getDisplay(), "_MOTIF_WM_HINTS", True ) ;

   if ( prop == 0 )
     return ;

   /* not sure this is correct, seems to work, XA_WM_HINTS didn't work */

   proptype = prop ;

   XChangeProperty( disp->getDisplay(), Handle,
                    prop, proptype,                 /* property, type */
                    32,                             /* format: 32-bit datums */
                    PropModeReplace,                /* mode */
                    (unsigned char *) &motif_hints, /* data */
                    PROP_MOTIF_WM_HINTS_ELEMENTS    /* nelements */
                  ) ;
