Adding a JComponent on top of full-screen-graphics

I have a fullscreen program, which draws a lot of things for the game I am making. The canvas is the entire 开发者_JS百科window, which it should be. Now I want to add a button, or textfield (JButton and JTextField etc...) to my window. However, when I add a button, or anything else, they go begind the canvas.

Do you have any idea how to get the button to show up ON the canvas, so I can click it?

Edit: Drawing code:

public synchronized void draw(Graphics2D g) {
        if (!welcome)
            g.drawImage(background,0,0,null);

        if (welcome) {
            g.drawImage(new ImageIcon (getClass().getResource("images/backgroundWelcome.jpg")).getImage(), 0,0, null);
        }
        else if (gettingName) {
            setFont (new Font("Verdana", Font.ITALIC, 40));

            g.draw3DRect(center.x -325, center.y -50, 650, 100, true);
            g.drawString("Please enter your name", center.x -250, center.y -120);
            g.drawString(name, center.x -315, center.y);
        }
        if (game) {
            for (Player p: player) {
                int x = center.x;
                int y = center.y;

                switch (p.getID()) {
                case 1:
                    x -= name.length()*10;
                    y *= 1.4;
                    break;
                case 2:
                    x -= name.length()*10;
                    y /= 1.4;
                    break;
                case 3:
                    x *= 1.4;
                    x -= name.length()*10;
                    break;
                case 4:
                    x *= 0.6;
                    x -= name.length()*10;
                    break;
                default:
                    System.out.println("Error 2");
                }
                g.drawString(p.getName(),x,y);
            }
            for (int x = 0; x<13; x++) {
                g.drawImage(diamonds[x].getImage(), (int) diamonds[x].getX(), (int) diamonds[x].getY(), null);
                g.drawImage(clubs[x].getImage(), (int) clubs[x].getX(), (int) clubs[x].getY(), null);
                g.drawImage(hearts[x].getImage(), (int) hearts[x].getX(), (int) hearts[x].getY(), null);
                g.drawImage(spades[x].getImage(), (int) spades[x].getX(), (int) spades[x].getY(), null);
            }
            g.drawImage(put.getImage(), (int) put.getX(), (int) put.getY(), null);
        }

        if (won) {
            g.drawImage(new ImageIcon (getClass().getResource("images/backgroundWelcome.jpg")).getImage(), 0,0, null);
        }
        else if (lost) {
            g.drawImage(new ImageIcon (getClass().getResource("images/backgroundWelcome.jpg")).getImage(), 0,0, null);
        }
    }

Edit2: My frame is a JFrame.

It is difficult to tell much from the code snippet (please consider posting an SSCCE in future), but:

1. Don't code AWT in this millennium.
2. Don't mix Swing with AWT (at least until Java 7)
3. Don't load images within the draw() method (which is presumably called from the paintComponent() method).
4. Note that custom painting in Swing can be done in a JComponent or JPanel and that if the class is the latter, it can have a layout with other components added.

You are painting the canvas yourself so you will need to add the button elsewhere or paint an area that looks like a button and check if mouse events fall inside the button's area.
