Is it that it's MDI at all? If so then Swing does MDI with JDesktopPane.

If you talking about the particular look of that MDI application then you can look for existing Swing LnFs that might approximate that look (or design your own), or use undecorated JInternalFrames and paint them any way you like.

Note that the Windows LAF is only available under Windows; on other platforms this will select the OS X or Motif or GTK LAF, whatever is appropriate.
