Java JOptionPanel change text field with TAB
So I don't really know anything about Frames, Windows, or Panels.. I just got interested in Java because a coworker is doing classes in it. I know some other languages but never did GUI things...I literally just got NetBeans, and drew up a dialog using it's Design view.

All I want is for the TAB key to go to the next textfield. What's the simple way?

Code:
package com.neutronscott;
import javax.swing.JOptionPane;
public class hw1 {
    public static void main(String[] args) {
        InputPanel myPanel = new InputPanel();
        JOptionPane.showMessageDialog(null, myPanel);
        System.out.println("Name: " + myPanel.getFirstName() + " " myPanel.getLastName());
    }
    
}

That's all I got. The dialog that it created is a lot. I'll keep it brief:

Code:
package com.neutronscott;

public class InputPanel extends javax.swing.JPanel {

    public InputPanel() {
        initComponents();
    }

    /**
     * This method is called from within the constructor to initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is always
     * regenerated by the Form Editor.
     */
    @SuppressWarnings("unchecked")
    // <editor-fold defaultstate="collapsed" desc="Generated Code">                          
    private void initComponents() {

        jScrollPane2 = new javax.swing.JScrollPane();
        firstName = new javax.swing.JTextPane();
        jScrollPane3 = new javax.swing.JScrollPane();
        lastName = new javax.swing.JTextPane();
        jScrollPane4 = new javax.swing.JScrollPane();
        age = new javax.swing.JTextPane();
        jLabel1 = new javax.swing.JLabel();
        jLabel2 = new javax.swing.JLabel();
        jLabel3 = new javax.swing.JLabel();

        jScrollPane2.setViewportView(firstName);

        jScrollPane3.setViewportView(lastName);

        jScrollPane4.setViewportView(age);

        jLabel1.setText("First Name");

        jLabel2.setText("Last Name");

        jLabel3.setText("Age");

        javax.swing.GroupLayout layout = new javax.swing.GroupLayout(this);
        this.setLayout(layout);

I'm thinking probably because it needs a JFrame around it to inherit all the default focus stuff.
