I've got an application that monitors our internet connection at work and displays its current status in the system tray on Windows boxes using Win32::GUI. I would like to modify the application to work under Linux. It would be easy to do using Perl/Tk or a variety of other options however the piece of the puzzle I haven't been able to find is how I can make any of those applications dockable, specifically under Gnome. Anyone have any experience or information on this?
