I would like to know what code to insert and where to add a simple label that can just say the word "Label" and a input text box that I can enter a number.

public CalculateDimensions() {

    JTabbedPane Tab = new JTabbedPane();
    JPanel jplInnerPanel1 = createInnerPanel("First Tab");
    Tab.addTab("One", jplInnerPanel1);
    Tab.setSelectedIndex(0);
    JPanel jplInnerPanel2 = createInnerPanel("Second Tab");
    Tab.addTab("Two", jplInnerPanel2);
    JPanel jplInnerPanel3 = createInnerPanel("Third Tab");
    Tab.addTab("Three", jplInnerPanel3);
    JPanel jplInnerPanel4 = createInnerPanel("Fourth Tab");
    Tab.addTab("Four", jplInnerPanel4);
    JPanel jplInnerPanel5 = createInnerPanel("Fifth Tab");
    Tab.addTab("Five", jplInnerPanel5);

    setLayout(new GridLayout(1, 1));
    add(Tab);
}
protected JPanel createInnerPanel(String text) {
    JPanel jplPanel = new JPanel();
    JLabel jlbDisplay = new JLabel(text);
    jlbDisplay.setHorizontalAlignment(JLabel.CENTER);
    jplPanel.setLayout(new GridLayout(1, 1));
    jplPanel.add(jlbDisplay);
    return jplPanel;
}
public static void main(String[] args) {
    JFrame frame = new JFrame("Calculations");
    frame.addWindowListener(new WindowAdapter() {

        public void windowClosing(WindowEvent e) {
            System.exit(0);
        }
    });
    frame.getContentPane().add(new CalculateDimensions(),
            BorderLayout.CENTER);
    frame.setSize(400, 400);
    frame.setVisible(true);
}

}
