Is it possible to have windows with sliding frames within it?

A sliding frame would be an area with buttons and other controls
which could be moveable using scroll bars. That way, we could
have like a huge panel of controls that we could "slide" using a
scroll bar in order to uncover those controls that doesn´t fit on
the window.
