Add a JPanel to a Graphics Panel and making the JPanel Transparent except for objects

Question

I am trying to make a Blackjack Game and way I want to design my program is with a graphics panel (Images, drawing of cards, etc.) and on top of that panel a JPanel with buttons. I want this JPanel to be transparent so that the Graphics Panel underneath is Visible but the JButtons do not turn transparent as well.

If someone can send me in the right direction?

Graphic Layer:

public class GraphicsBoard {
    String[] fileName = { "cards.png", "BlackJackBoard.png" };
    ClassLoader cl = GraphicsBoard.class.getClassLoader();
    URL imgURL[] = new URL[2];
    Toolkit tk = Toolkit.getDefaultToolkit();
    Image imgCards, imgBG;

    public GraphicsBoard() throws Exception {
        for (int x = 0; x < imgURL.length; x++)
            imgURL[x] = cl.getResource("pictures/" + fileName[x]);
        imgCards = tk.createImage(imgURL[0]);
        imgBG = tk.createImage(imgURL[1]);
    }

    public void paintComponent(Graphics g) {
        g.drawImage(imgBG, 0, 0, 550, 450, 0, 0, 551, 412, this);

        Graphics2D g2 = (Graphics2D) g;
        for (int x = 0; x <= 550; x += 50) {
            g2.drawLine(x, 0, x, 450);
            g2.drawString("" + x, x + 5, 20);
        }
        for (int y = 5; y <= 450; y += 50) {
            g2.drawLine(0, y, 550, y);
            g2.drawString(" " + y, 0, y + 20);
        }
    }
}

Button Layer:

public class OverBoard extends JPanel implements ActionListener{
    JButton btnDeal = new JButton("Deal");

    public OverBoard(){
        btnDeal.addActionListener(this);
        add(btnDeal);
        setOpaque(false);
    }
}

I want the ButtonLayer to be on top of the GraphicLayer.

there are a few ways, proper could be to

use GlassPane, have to consume() or redispatch KeyEvents
JLayer (Java7), based on JXLayer(Java6)
