        getContentPane().setLayout(new org.netbeans.lib.awtextra.AbsoluteLayout());

        jLabel1.setText("DVD Library");
        getContentPane().add(jLabel1, new org.netbeans.lib.awtextra.AbsoluteConstraints(168, 11, -1, -1));

        jLabel2.setText("What would you like to do today?");
        getContentPane().add(jLabel2, new org.netbeans.lib.awtextra.AbsoluteConstraints(113, 70, -1, -1));

        jButton1.setText("Create Record");
        jButton1.addMouseListener(new java.awt.event.MouseAdapter() {
