Is being awarded a penalty against a team enough of a punishment?

Uruguay beat Ghana after Ghana missed a penalty in the dying seconds of the game. Ghana were awarded a penalty because Uruguayan striker Suarez deliberately handled the ball on his own goal line. So rather than awarding a penalty which could be missed or saved and so giving the offending team a second chance, should the referee be able to award a 'penalty goal' rather as in rugby where a referee can award a 'penalty try' should he believe that a try has been prevented by the defending team's misconduct?

An interesting question posed to me by a rugby fan friend over the past weekend; does he have a point?
