How to make a simple form layout without ad RAD tool

Question

I'm trying to make a simple form, but I'm not finding the right layout manager to make the components goes in Y axis. The BoxLayout could solve my problem, if it does not fill all the panel with the components.
My SCCEE:
public class TestSimpleForm extends JPanel {
    JLabel nameLbl = new JLabel("Name:");
    JTextField nameField = new JTextField();
    JButton okBtn = new JButton("OK");
    JButton cancelBtn = new JButton("Cancel");
    public TestSimpleForm() {
     add(nameLbl);
     add(nameField);
     add(okBtn);
     add(cancelBtn);
    public static void main(String[] args) {
     JPanel panel = new TestSimpleForm();
     // if i make it a boxlayout panel, the text field size goes huge
//     panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
     JFrame f = new JFrame();
     f.setContentPane(panel);
     f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     f.setSize(400, 600);
     f.setLocationRelativeTo(null);
     f.setVisible(true);
}
