The example you are giving is rather static. You could also go for a more dynamic approach where you override the onDraw method of a View:

public class MyView extends View {
    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        Paint p = new Paint();
        p.setColor(Color.BLACK);
        canvas.drawRect(10, 10, 10, 10, p);
        p.setColor(Color.WHITE);
        canvas.drawText("Ohai!", 0, 5, 20, 20, p);
    }
}

You just then put this View on your panel where you want it. There are of course even more methods to use for this, just have a look at the Canvas class

Or you could of course just some kind of TextView you can customize (add some borders etc).
