I believe my 2D Overlay solution will work for your situation, although I didn't have time to look at your code.
I think by setting the OverlayPanel as the GlassPane of the parent JFrame (see setGlassPane), then setting the OverlayPanel visible, the OverlayPanel will intercept the mouse behaviors (don't forget to add the OverlayPanel as a mouse listener to the JFrame). (Look at the Java Sun Tutorials on Containers/GlassPanes/etc for more information about GlassPanes.) The OverlayGraphics is passed into the OverlayCanvas3D to display the 2D graphics (in my solution, the OverlayGraphics and OverlayPanel are one class) by drawing into the J3DGraphics2D context in the postRender method. Let me know if this works for you or if you have any more questions.
