Using GWT and the Google Maps component, how do I best create the "panel shadow" effect as seen in the screenshot?

Try the box-shadow CSS property (make sure the browsers you are targeting supports it)

-webkit-box-shadow: inset 3px 3px 5px 5px #000000;
-moz-box-shadow: inset 3px 3px 5px 5px #000000;
box-shadow: inset 3px 3px 5px 5px #000000;

Use rgba color spec with opacity to get a "lighter" shadow.
