You might look into metaphase editor, "A WYSIWYG HTML Editor Component for use in Java Applications." It's based on Charles Bell's HTMLDocumentEditor.

Basically, to draw grids and lines, you need to draw the HTML elements graphically on one or more JPanels.

You do this by overriding the paintComponent() method with your Graphics and Graphics2D method calls.

Here's a simple example:

 public void paintComponent(Graphics g) {
    // Dynamically calculate size information
    Dimension size = getSize();
    // diameter
    int d = Math.min(size.width, size.height); 
    int x = (size.width - d)/2;
    int y = (size.height - d)/2;

    // draw circle (color already set to foreground)
    g.fillOval(x, y, d, d);
    g.setColor(Color.black);
    g.drawOval(x, y, d, d);
}
