Wich function (class) could I use to create one pixel high object (frame)?

Question

Hi guys, I need a pointer on a certatin line on the graphic screen. And I want it to be written in Java. I know how to make it to be "always on top" now, but AFAIK every applet or application is to be shown in a bordered window saying it is a Java object for security reasons. As I want it to be one pixel high, I apparently need to get rid of the frame border. Supposedly I have to switch off the security, but it's OK for me.
Wich function (class) do I use to create one pixel high object?
And one more thing. How do I generally show a graphic object of nonrectangular shape out of the bordered frame? Is there a way to do it without creating an transparent rectangular window/frame?

I didn't quite know what you mean, but how's this?
public class MySinglePixelWindow extends JWindow {
   public MySinglePixelWindow() {
      super();
      setSize(1,1);
      setLocation(0,0);
   public void paint(Graphics g) {
      super.paint(g);
      g.fillRect(0,0,1,1);
}Transparent Window:
public class MyTransparentWindow extends JWindow {
   java.awt.Robot robot;
   BufferedImage screen;
   public MyTransparentWindow() {
      super();
      try {
         robot = new Robot();
      } catch(Exception e) {}
   public void show() {
      image = robot.createScreenCapture(getBounds());
      super.show();
   public void paint(Graphics g) {
      super.paint(g);
      Graphics2D g2 = (Graphics2D)g;
      g.setComposite(AlphaComposite.newInstance(AlphaComposite.SRC_OVER,0.8));
      g.drawImage(image,0,0,this);
}Puh!
You can't move this window though...
