You need to lay out the user interface components visually, by hand, with total control over where they go. Automated LayoutManagers don't cut it. A corollary of this is that you can't move a UI layout from one platform to another and have the computer make everything fit. Computers don't lay out interfaces by themselves any better than they can translate French to English by themselves.
