private void formWindowOpened(java.awt.event.WindowEvent evt) {                                  

        // create header panel
        JPanel hPanel = new JPanel();
        hPanel.setLayout(new BorderLayout(600, 100));
        this.getContentPane().add(hPanel);

        // text header
        JLabel hLabel = new JLabel("LỊCH VẠN NIÊN 2015");
        hPanel.add(hLabel);

    }

hPanel.setLayout(new BorderLayout(600, 100));

That means gap between compponents is 600 (horizontal) and 100 (vertical). Nothing related to size.

Try setPreferredSize() instead but it's not recommended. It's better to reflect sizes of componnets rather than define your own.

Also move the 

this.getContentPane().add(hPanel);

to the method end to be the last statement.

You may also need to call pack() or setSize() of the frame.
