Look at the phone message card in the Stack Ideas stack.
Those check boxes on the right hand side might as well be
radio buttons; the method used for the boxes will work just
well for what you want to do.  The basic idea is to make an
invisible field which holds the word "true" or "false," or
whatever you want it to say, which corresponds to a on or
off state for the button.  Then when the button is clicked
have the script check the contents of the field, toggle the
value, and highlight or unhighlight the button accordingly.
