Splitting a window into tabs?

[Seagoat]

Hey guys! I've got what I think is a great mod for the Voice Options window (see attached), but unfortunately the contents of the tab pages don't actually do anything in-game...they don't show the correct data or allow you to manipulate anything. It looks great, and the tabs work, but nothing else.

So is it even possible to create a fully functional tabbed version of an existing non-tabbed window? The answer's probably no, but I'm cautiously optimistic...
