BorderLayout align

Question

I have a JPanel with a BorderLayout. In the Center of this JPanel I have another JPanel with GridBagLayout. I want to add vertically in the second JPanel some JLabels from top left corner. I need BorderLayout because I need to add my title in the North area.

How can I achieve this?

You don't really need the GridBagLayout, you can use easier BoxLayout:

public class Popup {
  public static void main(String[] args) {
      JFrame window = new JFrame("Title");

      window.add(new JLabel("North", JLabel.CENTER), BorderLayout.NORTH);
      window.add(new JLabel("South", JLabel.CENTER), BorderLayout.SOUTH);
      window.add(new JLabel("West"),  BorderLayout.WEST);
      window.add(new JLabel("East"),  BorderLayout.EAST);

      JPanel centerPanel = new JPanel();
      centerPanel.setLayout(new BoxLayout(centerPanel, BoxLayout.Y_AXIS));

      centerPanel.add(new JLabel("Here"));
      centerPanel.add(new JLabel("Here"));
      centerPanel.add(new JLabel("Here"));
      centerPanel.add(new JLabel("Here"));

      window.add(centerPanel, BorderLayout.CENTER);

      window.setSize(600, 400);
      window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      window.setVisible(true);
   }
}
