No, the buttons are mapped exactly as they were for the SNES. Virtual console games are only changed enough to make them play at all on the Wii, they don't spend anymore time than that. With a classic controller, the buttons are in the correct locations for how the SNES controller was laid out. LoZ LttP works just fine on the GC controller because the actions don't ever require you to hit two buttons (run+jump in SMW for example)
