I needed for my GWT project a panel that supports showing a set of widgets in a group (GroupBox panle). I needed the exact functionality like the HTML fieldset/legend tags:

It was really easy to extend the flow panel and add <fieldset> and <legend> tags around the panel element. Hope this widget will be useful to everybody. I may wish to modify the CSS to make it look better.
