Yes, I've included a simple Separator object below (note that it
only does "etched in", you might want to make its style a
configurable parameter).
You can also override the panel's paint method and draw your
decorations directly on the panel - they key here is to ensure
that whatever you are drawing isn't obscurred by any of the
panel's children (using Insets is a nice way to do this if you
just want a border).

g.setColor(darker);
g.drawLine(x1, y2, x2, y2);
