Swing uses a variant of MVC, which is explained in the Swing
architecture article on the Sun "Swing Connection" page. Swing does not
do the "pure" MVC thing.
You can find many examples of using Swing's widget/model combination in
Sun's GUI tutorial.

Already because of the fact that it is most likely a public class, it
has to end up in an own file (Java's rule about files and public
classes).

They do not exist in this form in Swing. So you have to make a
decission.
- You can use Swing's architecture, which works for practical purposes, but is not "pure" MVC.
- You "fight the system", and try to squeeze "real" MVC out of Swing.
- You implement an own GUI system, exactly doing MVC.

If it just uses Swing, it can't.
