To the right of that, the window is divided in two horizontally. The top right window shows what messages are in the folder I have selected on the left. The bottom right window is the "preview pane" showing me the contents of the message that I have selected in the top-right window.

I don't see here anything that can't be accomplished with a treeview on the left, a grid on top, and a web browser object on the bottom. You may need some splitter bars, though.
