CODE

        addButton.addActionListener(new ActionListener()
        {

            public void actionPerformed(ActionEvent e)
            {


This does not make sense.. adding an actionListener to a button in your actionPerformed method
and your button name is not "addButton" but "btnAdd"

replace the preceeding lines by:

if(buttonPressed == btnAdd)
{

re-align your { and } and you should be on a better track

same thing for the other buttons for the replace, delete, ....
