Custom scrollbar

in flash8/mx04 is it possible to create a custom scrollbar for text only?
i would like to make a dynamic text field with a scrollbar that doesnt need to be contained in a masked mc like most of the scrollers i have seen on this forum so far. i dont want to use the UIscrollBar component because it doesnt quite (well, doesnt at all) fit in with the theme of the project i am working on.

so, anyone have any suggestion on how to make a scrollbar?
