There's probably a faster way, but the way I know is remapping the ';'
key like this:

(global-set-key ";" 'insert-closepar)

where the function insert-closepar would be something like this
(tested) :

(defun insert-closepar ()
 "Close parenthesis Jiri's way"
  (interactive)
  (if (looking-at ")")
                (forward-char))
  (insert ";"))

Oh, and you probably don't want to make that binding global map,
because you are only going to use it on specific modes. Try doing:
 (define-key somelanguage-mode-map ";" 'insert-closepar)

Hope I could help,
