Gridbag Layout

My problem is as follows: I´m making a gridbag with 3 rows and in the second row I have to split up the cells or insert a panel. That´s because of the things I´m putting in ém. Choosing the panel leads me to following question: Where am I going to declare the panel and where should the gridbag in the panel in the gridbag (!) be placed?



import java.awt.*;
public class Rapport extends
java.applet.Applet
{
        Panel Pane = new Panel();
        void buildConstraints(GridBagConstraints gbc, int gx, int gy, int gw, int gh, int wx, int wy)
        {
            gbc.gridx = gx;
            gbc.gridy = gy;
            gbc.gridwidth = gw;
            gbc.gridheight = gh;
            gbc.weightx = wx;
            gbc.weighty = wy;
            add(Pane);
        }
                public void init()
                {
        GridBagLayout gridbag = new GridBagLayout();
        GridBagConstraints constraints = new GridBagConstraints();
        setLayout(gridbag);
        Pane.setLayout(gridbag)
        //label
        buildConstraints(constraints, 0, 0, 1, 1, 33, 0);
        constraints.fill = GridBagConstraints.BOTH;
        constraints.anchor = GridBagConstraints.WEST;
        Label label01 = new Label("Kundenummer", Label.LEFT);
        gridbag.setConstraints(label01, constraints);
        add(label01);
                .
                .
            //Panel 
        buildConstraints(constraints, 0, 0, 1, 1, 50, 0);
        constraints.fill = GridBagConstraints.BOTH;
        constraints.anchor = GridBagConstraints.WEST;
        Label PanLabel1 = new Label("1", Label.LEFT);
        gridbag.setConstraints(PanLabel1, constraints);
        Pane.add(PanLabel1);
        //Panel
        buildConstraints(constraints, 1, 0, 1, 1, 50, 0);
        constraints.fill = GridBagConstraints.BOTH;
        constraints.anchor = GridBagConstraints.WEST;
        Label PanLabel2 = new Label("2", Label.LEFT);
        gridbag.setConstraints(PanLabel2, constraints);
        Pane.add(PanLabel2);
            //Label
        buildConstraints(constraints, 2, 0, 1, 1, 33, 0);
        constraints.fill = GridBagConstraints.BOTH;
        constraints.anchor = GridBagConstraints.WEST;
        Label label12 = new Label("            Dato                    Reparatør", Label.LEFT);
        gridbag.setConstraints(label12, constraints);
        add(label12);
                .
                .
