The XmLabel widget has the XmNsensitive resource. If set to true it will
display the XmNlabeString "grayed out" and it won't activate the button.
To set the sensitivity via the application state, you should keep the
widget ID of the button around (ie. use MrmNcreateCallback if UIL) and
change the XmNsensitive resource using XtSetArg/XtSetValues.
