Java Swing - how to show a panel on top of another panel?

I wish to have an internal (non window) dialog to ask for member input. I would like the dialog to be placed centrally on an existing JPanel.

I have looked at layeredpanes and these seem unusable due to only having a single layout manager (or no layout manager) across all the panes. I guess I could try to override JLayeredPane and provide a custom layout but this seems extreme.

Glass panes don't seem to be appropriate either.

How can this be done? Is there no usable concept of z-indexes in Swing?

EDIT

The reason Layered Panes weren't appropriate was due to the lack of a layout manager per layer. The panel is resizeable, Panel A should stay at 100% of area and Panel B should stay centralized.

Use a 1 by 1 GridLayout on the existing JPanel, then add your Panel to that JPanel. The only problem with a GridLayout that's 1 by 1 is that you won't be able to place other items on the JPanel. In this case, you will have to figure out a layout that is suitable. Each panel that you use can use their own layout so that wouldn't be a problem.

Am I understanding this question correctly?
