Please read How To Use Swing Timer and The Event Dispatch Thread.

Use then javax.swing.Timer to re-read the data from database and set the content on the JTextField the way you need it.

Timer timer = new Timer(3000, new ActionListener() {

    @Override
     public void actionPerformed(ActionEvent e) {
         .... // retrieve data and prepare the textField content
         textField.setContent(...);
     }          
});

timer.start();
