[R-gui] Another R-GUI
The level isn't terribly critical -- we will need both, to describe both fine grained as well as higher level control of widgets, especially if there is to be any hope for crafting similar UIs.
While they can initially be hardcoded, flex-coding the underlying components will be preferred in the long run.
Ok, how about this for a compromise: Let's try to start out with as few and as complex/high level widgets as possible, and then slowly add more flexibility as the limitations become visible?
