Panel - animacja i komponenty

Jak stworzyć panel na którym będą małe panele i będzie także przeprowadzona animacja grafiki(kwadraty,linie,koła). Do tego chce mieć możliwość przesuwania tych wewnętrznych paneli co mam zrealizowane ale po przeciążeniu metody paint() wszystko znika.

Mam coś takiego:

public class JPanelSuper extends JPanel implements MouseMotionListener{
    static public JPanelSuper INSTANCE ;
    public int x,y;
    public JLabel jLabel;
    public JPanelMy jPanelMy;// = new JPanelMy();
    public JPanelMy jPanelMy2;// = new JPanelMy();
    public Line2D line2D;
    /* Constructor */
    public JPanelSuper() {
        INSTANCE = this;
        this.setLayout(null);
        jLabel = new JLabel();
        jLabel.setBackground(Color.green);
        jLabel.setText("Label");
        jLabel.setLocation(100, 20);
        jLabel.setSize(200, 20);
        this.add(jLabel);
//        for (int i = 0; i < 2; i++) {
//            this.add(new JPanelMy());
//        }
        
        jPanelMy = new JPanelMy();
        jPanelMy2 = new JPanelMy();
        this.add(jPanelMy);
        this.add(jPanelMy2);
        this.addMouseMotionListener(this);
        /*MyCanvas*/
//        MyCanvas canvas = new MyCanvas();
//        canvas.setSize(50, 50);
//        canvas.setLocation(20, 20);
//        canvas.setBackground(Color.red);
//        canvas.setPencilMode();
//        canvas.setLineMode();
//        //canvas.addComponentListener(new JPanelMy());
//        this.add(canvas);
    }
    public void mouseDragged(MouseEvent e) {
        //throw new UnsupportedOperationException("mouseDragged");
    }
    public void mouseMoved(MouseEvent e) {
        x = e.getX();
        y = e.getY();
        jLabel.setText(x+" "+y);
        //throw new UnsupportedOperationException("mouseMoved");
    }
    public void paintNode() {
        Graphics graphics = this.getGraphics();
        Graphics2D g2 = (Graphics2D) graphics;
        this.update(g2);
        g2.setColor( new Color( 20, 20, 100));
        //g2.drawLine(30, 30, 200, 200);
        //g2.drawLine(jPanelMy.getX(), jPanelMy.getY(), jPanelMy2.getX(), jPanelMy2.getY());
        int tx1,tx2,ty1,ty2;
        tx1 = jPanelMy.getX() + (jPanelMy.getHeight()/2);
        ty1 = jPanelMy.getY() + (jPanelMy.getWidth()/2);
        tx2 = jPanelMy2.getX() + (jPanelMy2.getHeight()/2);
        ty2 = jPanelMy2.getY() + (jPanelMy2.getWidth()/2);
        g2.drawLine(tx1, ty1, tx2, ty2);
        //line2D.contains(1, 1, 50, 30);

        //line2D.setLine(1, 1, 100, 20);
        //this.removeAll();        
    }
    @Override
    public void updateUI() {
        super.updateUI();

    }

//    @Override
//    public void paint ( Graphics g ) {
//        jPanelMy.repaint();//this.repaint();
////przesuniecie układu wspolrzednych
//        g.setColor( new Color( 20, 20, 100));
//        g.drawLine(30, 30, 200, 200);
//    }
}
