For that kind of thing I would recommend using the FormLayout. It is a 
bit more complex and takes longer to learn than the others, but I think 
it is the only one that does not depend on the order in which the 
widgets were added to the parent. In other words, it will allow you to 
dynamically re-arrange the widgets after they have been created.
Remember that when you change the layout datas for the widgets (to 
re-position them) you'll need to call layout() on the parent Composite.

Hope this helps,
