 * if you want add some options, so it's not really difficult
 * 1: Learn Motif ... but only if you want to :)
 * 2: add a name of widget after geometry,font,program
 * 3: add a string ( char * ) after *inval=NULL,*geo=NULL
 * 4: add a callback like f_username with your new string
 * 5: copy and paste after
   geometry=XtVaCreateManagedWidget("geometry",xmPushButtonGadgetClass,options,NULL);
   XtAddCallback(geometry,XmNactivateCallback,f_geometry,NULL);
 *    change geometry by your name of widget, and f_geometry by the name
 *    of your new callback
 * 6: go to the church , call god for a miracle :)
 * GOOD LUCK
