I am looking for a tool that would allow me to have 3 sizable areas on a form where I would display a ListBox, TreeView, Grid, or Editbox. I want all three regions to resize based on the resizing of any one display area. Any ideas?

I tried setting this us usding a FormSet consisting of 3 forms and was able to achieve the basic goal of being able to resize the various objects / forms based on the resizing on any one of the forms. The problem is, it does not provide the windows explorer look & feel. The use of the sizeable boarder produces too many line.
