Answer 1

Have your constructor be separate from the main method, and have its name be the same as your class name (i.e. public Panel_Test since the name of your class is Panel_Test).

public class Panel_Test extends JFrame {
    public Panel_Test() {
        // code here
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                new Panel_Test();
            }
        });
    }
}

Don't forget to do your Swing operations on the Event Dispatch Thread, using javax.swing.SwingUtilities.
