Ok so that works (calling setHorizontalAlignment() before widgets are
added). So now the labels are horizontally centered.
Still can't seem the vertically center them though. I think it's because
the VerticalPanel keeps wrapping its contents vertically, even though I've
set its height to 100% (the red area is the VerticalPanel with height=100%):

Any ideas here?
Thanks
