                    JButton bt = new JButton("Completed");
                    bt.addActionListener(new ActionListener() {

                        @Override

                        }

                }

                @Override

                    // TODO Auto-generated method stub

        protected void paintComponent(Graphics g) {
            super.paintComponent(g);
            Font font = new Font("Helvetica", Font.BOLD, 14);
            FontMetrics fm = g.getFontMetrics(font);
            int w = fm.stringWidth(phrase);
            int h = fm.getAscent();
            g.setFont(font);
            g.drawString(phrase, getWidth() / 2 - w / 2, getHeight() / 2 + h
                    / 2);
        }

        @Override
        public Dimension getPreferredSize() {
            return new Dimension(100, 20);
        }

        public void setXLoc(int xLoc) {
            this.xLoc = xLoc;
        }

        public int getXLoc() {
            return xLoc;
        }
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                new TestLabelMove();
            }
        });
    }
}

This code also taken from net to learn. It exactly matches my requirement.After removing label on mouse click, it should disappear from scrolling labels from Frame.
