The pure-Java way is to use ImageIO to load the image as a BufferedImage. Then you can call createGraphics() to get a Graphics2D object; you can then draw whatever you want onto the image.

You can use an ImageIcon embedded in a JLabel to do the displaying, and you can add a MouseListener and/or a MouseMotionListener to the JLabel if you're trying to allow the user to edit the image.
