"scripts" are entirely different from GUI applications. What do you expect to happen when you run a Swing application through telnet on another machine? Do you expect the Swing UI to be magically transported to the local Windows machine?
Not gonna happen. Yes, like ejp hinted, you could run an X-environment on your local machine and have the Swing UI tunnel its output there, but are you sure you want GUI apps to run on a remote machine like that? It's not gonna be fun to work with, I'll tell you that.
Why not create a Java WebStart app (or perhaps even an applet) out of your application, so your users can run the application locally?
