Torsten already gave you the correct answer. However, here are some rough
code fragments which show what Torsten means:

...
public class FTPApp extends JFrame
{
  ...
  ...
  protected JButton startButton;
  protected JButton stopButton;
  ...
  protected FtpClient ftpClient;  // <- class sun.net.ftp.FtpClient
  ...
 public FTPApp() {
  ...
  ...
  startButton = new JButton("Start");
  lst = new ActionListener() {
    public void actionPerformed(ActionEvent e) {
      if (connect()) {
        Thread downloader = new Thread() {
           public void run() {
              getFile();  // your getFile method or similar
              disconnect();
          }
        };
        downloader.start();
     }
   }
  };
  ...
  ...
 }

  public void setButtonStates(boolean state) {
    startButton.setEnabled(state);
    stopButton.setEnabled(!state); // always inverse the state here
  }

...
  protected boolean connect() {
    ...
    setButtonStates(false);
   ...
  }
...
protected void disconnect() {
  if (ftpClient != null) {
    try { ftpClient.closeServer(); }
    catch (IOException ex) {...}
    ftpClient = null;  // for garbage collection
 }
 Runnable runner = new Runnable() {
   public void run() {
     ...
     setButtonStates(true);
     ...
   }
 };
 SwingUtilities.invokeLater(runner);
}
...
...
}
