Simple layout, how can I create it?

Hi, I’d like to create the Main Scrren of my aaplication, such as we do with Tables/Divs (HTML), I have use the GridLayout, VerticalLayout but it didn’t work to me, I’d like to create a Layout such as the attach file.

I’d like to create a TOP, CENTER and Botton spaces, the Center I’d like to put a SplitHorizontalPanel, any help?

A VerticalLayout with a HorizontalScrollbar in the middle will work just fine.
