Was I wrong to not say anything?

There is nothing wrong with telling someone they look beautiful. That can be to anyone, even your friend's wife. It is not bad or weird as long as you do not go into too much detail as that can become a bit too much for some people, but you could have said she looks beautiful :) However if to you, it felt odd, then it is perfectly OK to not have said anything either but for a formal event like that it is perfectly appropriate to compliment other people :)
