Seems like more of a SWT question to me but I will see if I can help.

In general you need to build your full layout then hide the widgets you
don't want to see. When they press the button you make widgets visible.
I don't believe, and I could be wrong, that you can add a widget to a
composite later. They all must be there from the start and you can show
and hide them as needed from there.

If you call composite.layout(true), it should make the widget appear.
