You create the buttons contiguously (eg. buttons 4 to 8)
and then in each button, you put a script like
on mouseUp
  family
end mouseUp

and then define in card or stack script:

on family
  repeat with i = 4 to 8
    set hilite of button i to false
  end repeat
  set hilite of target to true
end family

Uhh, I've not written in hypertalk for a while and I can't remember the
exact syntax of the for loop (C and Pascal and BASIC all have totally
different syntax) but the idea's the same.
