Using XmATTACH_POSITION is the right idea, but if you use it for one side
of CLOSE, then it's not centered.  If you use it for both sides of CLOSE,
then you still get the button growing.

What you need to do is have a new widget called CENTER which has height and
width of 0, and uses XmATTACH_POSITION of 50.  You then use XmATTACH_WIDGET
to attach CLOSE to CENTER.  Here is the relevent uil code:

    object Center : XmSeparator widget {
        arguments {
            XmNseparatorType = XmNO_LINE;
            XmNheight = 0;
            XmNwidth = 0;
            XmNleftAttachment = XmATTACH_POSITION;
            XmNleftPosition = 50;
            XmNrightAttachment = XmATTACH_POSITION;
            XmNrightPosition = 50;
        };
    };
    
    object Close : XmPushButton widget {
        arguments {
            XmNlabelString = 'Close';
            XmNleftAttachment = XmATTACH_WIDGET;
            XmNleftWidget = XmSeparator Center;
            XmNleftOffset = - (buttonWidth / 2);
            XmNrightAttachment = XmATTACH_WIDGET;
            XmNrightWidget = XmSeparator Center;
            XmNrightOffset = - (buttonWidth / 2);
        };
    };
