Transparent,Unclickable and unfocusable window in Java

I want a small window to be opaque and cant get focus with any clicks, Like a ghost.
I want that when I click on the java window, nth happens and the bellow window(s) takes the mouse action!
have tried these :

> Frame.java

import java.awt.BorderLayout;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTabbedPane;

public class Frame extends JFrame {
	JPanel panel;

	public Frame() {
		this.setBounds(100, 100, 200, 300);
		this.setDefaultCloseOperation(this.EXIT_ON_CLOSE);
		
		this.setResizable(false);
		this.setAlwaysOnTop(true);
		this.setUndecorated(true);
		this.setAutoRequestFocus(false);
		
		
		this.setOpacity((float) 0.5);
		this.setFocusable(false);
		this.setFocusableWindowState(false);
		this.setFocusCycleRoot(false);
		
		panel = new JPanel();
		getContentPane().add(panel, BorderLayout.CENTER);
		panel.setLayout(null);

		JTabbedPane tabbedPane = new JTabbedPane(JTabbedPane.TOP);
		tabbedPane.setBounds(37, 72, 107, 102);
		panel.add(tabbedPane);

		JLabel label = new JLabel("");
		label.setBounds(10, 10, 120, 20);
		panel.add(label);
	}
}

> Main.java

import java.io.IOException;

public class Main {

	public static void main(String[] args) throws IOException, ClassNotFoundException, InstantiationException {
		 Frame f = new Frame();
		 f.setVisible(true);
	}

}

my window appears transparent but it listens to my clicks when I click on it and I don't want it!
