You need to use two steps.  First, create the pushbutton with left attachment
to 50%.  Then, do an XtGetValues to get the width of the pushbutton.  Then,
do an XtSetValues to make the left offset be -width/2.

    Ratz put a bucket of liquid in front of me.
   "I wanted a glass of docs, Ratz.  What the hell is this?" I barked.
   "Motif don't fit in a glass anymore," he barked back.
    I looked at the liquid.  It was totally opaque to me.
