Write a text on JDeskopPane

I want to write a multiline text (3-4 lines is ok) on the bottom right corner of a JDesktopPane, how can I do this?
The text is not fixed, it can change every time i start the swing application but once the application is started it remains the same, I don't need to update from the application.

My first thought was to create an image, put it as background of the JDesktopPane and then write on it, but it doesn't seem a simple solution.

Thanks for the help.

Combining the examples seen here and here, the print() method in the variation below illustrates using FontMetrics to right justify multiple lines of text in the bottom, right corner of a JDesktopPane.

import java.awt.*;

public class JDPTest extends JDesktopPane {

    private MyFrame one = new MyFrame("One", 100, 100);

    public JDPTest() {
        this.setPreferredSize(new Dimension(640, 480));
        this.add(one);
    }

    @Override
    protected void paintComponent(Graphics g) {
        Graphics2D g2d = (Graphics2D) g;
        g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
            RenderingHints.VALUE_ANTIALIAS_ON);
        g2d.setColor(Color.lightGray);
        g2d.fillRect(0, 0, getWidth(), getHeight());
        g2d.setColor(Color.BLACK);
        g2d.setFont(new Font(Font.SERIF, Font.BOLD, 16));
        print(g2d, 3, "Hello, world!");
        print(g2d, 2, "This is a test.");
        print(g2d, 1, "This is another test.");
        print(g2d, 0, "This is still another test.");
    }

    private void print(Graphics2D g2d, int line, String s) {
        FontMetrics fm = g2d.getFontMetrics();
        int x = this.getWidth() - fm.stringWidth(s) - 5;
        int y = this.getHeight() - fm.getDescent()
            - line * (fm.getHeight() + fm.getLeading());
        g2d.drawString(s, x, y);
    }

        f.pack();
