I'm trying to create a form for a Task List, that will have a list of tasks sitting in a JScrollPane, with some buttons below it, to essentially look like this:

The problem I'm running into is that the scroll pane seems to be taking over the whole frame and I can't see the buttons. I'm working on a simpler prototype to try to figure out what I'm doing wrong, but nothing I've seems to work.

Can someone please help me to contain the size of the JSCrollPane?

public class Test extends JFrame {

    private JLabel label1 = new JLabel();
    private JLabel label2 = new JLabel();
    private JLabel[] titles;
    private JLabel[] descriptions;
    private JPanel[] panels;
    private JCheckBox[] boxes;
    private JScrollPane jScrollPane1;
    private JPanel bigPanel;
    private final static int NUM_OF_RESULTS = 10;

    public Test() {

        setLocationRelativeTo(null);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        this.setPreferredSize(new Dimension(1000, 600));

        bigPanel = new JPanel(new FlowLayout(FlowLayout.CENTER));
        //set layout to
        GridLayout layout = new GridLayout(30, 30);
        bigPanel.setLayout(layout);
        jScrollPane1 = new JScrollPane(bigPanel);
        jScrollPane1.setPreferredSize(new Dimension(500, 300));
        getContentPane().add(jScrollPane1);

        // How do I get these buttons to show on the main panel?
        // JButton button1 = new JButton("Save");
        // JButton button1 = new JButton("Cancel");
        // getContentPane.add(button1);
        // getContentPane.add(button2);

        scrollPanelDemo();
        pack();
        setVisible(true);
    }

    public void scrollPanelDemo() {

        titles = new JLabel[NUM_OF_RESULTS];
        descriptions = new JLabel[NUM_OF_RESULTS];
        panels = new JPanel[NUM_OF_RESULTS];
        boxes = new JCheckBox[NUM_OF_RESULTS];

        for (int i = 0; i < NUM_OF_RESULTS; i++) {

            String title = "Test Title " + i;
            String resume = "Test Resume " + i;

            titles[i] = new JLabel();
            boxes[i] = new JCheckBox();
            panels[i] = new JPanel();
            boxes[i].setPreferredSize(new Dimension(50, 50));
            panels[i].setPreferredSize(new Dimension(500, 50));
            panels[i].setLayout(new FlowLayout()); //FlowLayout is default for JPanel
            titles[i].setText(title);
            titles[i].setPreferredSize(new Dimension(500, 50));

            panels[i].add(boxes[i]);
            panels[i].add(titles[i]);
            bigPanel.add(panels[i], i, 0);
        }
    }

    public static void main(String args[]) {
        new Test();
    }
}
