Looking for… Widget boxes

Okay, I don’t know if what I want is possible, exists as a plugin, requires direct coding, or is simply impossible. I want to be able to create boxes around certain groups of widgets in the sidebar. I’d like to have the box have a title, and then some sort of visual distinction, whether it is an actual box, or a shaded area, around a set of widgets.

Right now, I’ve used the Text widget to create a title for the next few widgets below, but this isn’t ideal, as the Text widget’s text is the same size as the text for the titles of the widgets that follow, so it’s not clear that it’s a title for the entire group. Also, it’s hard to make it clear where the group ends and a new group begins.

Well, I hope that all makes sense. I’ve kept looking for a plugin that could actually do what I want, but I haven’t been able to find anything.
