If the layout is not too complicated, perhaps you can achieve what you want using the SplitContainer controls? Unfortunately, each SplitContainer will have only two "cells", but you can embed the SplitContainer in another SplitContiner panel to get more resizable cells:
ββββββββββββββββββββ
ββββββββ¬ββββββββββββ
ββ β ββ
ββ β ββ
ββββββββ΄ββββββββββββ
ββββββββββββββββββββ€
βββββββββββββ¬βββββββ
ββ β ββ
ββ β ββ
βββββββββββββ΄βββββββ
ββββββββββββββββββββ
OK, so ASCII art has never been one of my more powerful skills, but I think you understood that o)
