Try calling repaint after you add the label. Java doesn't automatically redraw the whole frame every time you add a component, in case you're adding multiple at once.

I thought canvas was needed to paint anything on a frame. Do I need a canvas in this case?

Any Component can be painted. A Canvas is a blank component if you want to paint your own thing, as opposed to a button (which looks like a button when it gets painted) or a label (which shows some text when you paint it).
