Nope no problem that I've ever expirienced, cuz all my PS2/NGC I played on an old school 4:3 CRT TV, and by the time I started playing games in 16:9 widescreen, I had got my PS3 and my HDTV, so all was good.
If the UI is stretched, then the game was never designed to be widescreen to begin with, and it was just an after thought, this happens to be the case for all consoles except the PS3 and 360.
