or a Dialog/JDialog including derivatives such as JOptionPane.showXXX().

Too many people ignore this. Layout managers are one of the best 
features of Java and make laying out resizable panels so much easier. 
Anyone new to layout managers could start with Sun's online tutorials. 
Anyone struggling with GridBagLayout could look at 3rd party layout 
managers like MigLayout (my favourite) and JGoodies FormLayout.
