    Show component in a frame, centered and packed, handling disposal with

	Display the component, centered and packed, in a Frame, JFrame, or 
	JInternalFrame.  Returns the frame.  If the GUI desktop is running then a 
	JInternaFrame will be used and automatically added to the desktop.  
	Otherwise if Swing is available a top level JFrame will be created.  
	Otherwise a plain AWT Frame will be created.
