    In fact your app is multi-threaded. Your main application thread is
    looped
    in the 'main' method. Whet you create gui, another thread (EDT) is
    started,
    and it takes care of all events (clicks, etc.).

    But as FISH fas mentioned, you may end up strangling the EDT.
    Make sure to put your main thread to sleep (inside while) for some
    short periods of time, or at least Thread.yeld(), to allow
    EDT do his job.
