Default set all components to be center of the JFrame

I used FormLayout and I want to set all my components(JLabel and JtextField) to be in the center of the JFrame.

I tried but it doesn't work.
shown below is my piece of code, please help thanks.

import java.awt.Component;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;

import com.jgoodies.forms.layout.CellConstraints;
import com.jgoodies.forms.layout.FormLayout;

public class UI extends JFrame {

	private JPanel panel = new JPanel();

	public UI() {
		FormLayout layout = new FormLayout(
				"pref, pref, pref, pref", 
				"pref, pref, pref, pref");
		CellConstraints cc = new CellConstraints();

		panel = new JPanel (layout);

		panel.add(new JLabel("L1 "), cc.xy(2, 2));
	    panel.add(new JTextField(15), cc.xy(3, 2));
	    panel.add(new JLabel("L2 "), cc.xy(2, 3));
	    panel.add(new JTextField(15), cc.xy(3, 3));

	public static void main(String args[]) {
		java.awt.EventQueue.invokeLater(new Runnable() {
			public void run() {
				// TODO Auto-generated method stub
				new UI().setVisible(true);
