You can do anything you want! Impossible is nothing.
Think about it like this... you can implement an algorithm that will compute
sizes for the panels and use the available API to create the visual
representation that you need. All you have to do is bind event handlers to
the relevant events (size changes in frame, move, etc) and then track the
values that you need like let's say size of the frame plus position of the
frame using local variables. Monitoring changes in both size and position
you can take a decision on how to change the inner panels sizes and then use
the SplitterWindow API to put the splitter in its right position.
