how would I make a start screen for a game using canvas?

I'm not looking for something advanced just New game and highscore link etc. The question might be stupid but I've never done anything similar and the tutorials out there don't cover the subject.

Is it enough to just make a fillText with onclick function? Is there a way to find out the size of the text?

Help appreciated.
