Creating Help pages

Question

I have designed a java program(GUI).
There is a button that brings up a help page when clicked,
like in microsoft word help.
How do i create this help page.

Answer 1

I have tested the html on a sample program.
It's not what i'm working on.But it keeps giving 2 errors.
error::invalid escape character at line 56
error::invalid escape character at line 56
N.B:The html file is stored on my hard disk
Can someone tell me why?
And i would appreciate any other suggestion to the problem i started
with at the begining of this thread(posting 1-5).
Here is the code:

     //create text field
     JTextField textField = new JTextField("Don't bustle me.", 15);
     textField.setFont(demoFont);
     //create password field
     JPasswordField passwordField = new JPasswordField("Don't now-then me.", 15);
     passwordField.setFont(demoFont);
     passwordField.setEchoChar('$');
     //create panel to contain text fields
     JPanel textFieldPane = new JPanel();

     GridBagLayout gridBag = new GridBagLayout();
     GridBagConstraints c = new GridBagConstraints();
     gridBag.setConstraints(textFieldPane, c);

        setBorder(BorderFactory.createEmptyBorder(20, 20, 20, 20));
    public static void main(String[] args) {
     JFrame frame = new JFrame("Eeyore Quotes");
     frame.addWindowListener(new WindowAdapter() {
             public void windowClosing(WindowEvent e) {
              System.exit(0);
     frame.getContentPane().add("Center", new EeyoreQuotes());
     frame.pack();
    frame.setSize(200,200);
    frame.setVisible(true);
