Well, if you must have the field go all the way to the lower-right corner of
the stack, then the answer is "yes", you'll have to make a non-scrolling
field, and have a separate scrollbar next to it. The hard part is knowing
how much of the non-scrolling field is scrollable so you can set the
endValue of the scrollbar. I guess you could subtract the height of the
field from the formattedHeight of the field to see what the difference is,
and if it is not negative, set the endValue of the scrollbar to that value.
Then, in the scrollbar, you just do:

  on scrollbarDrag
    set the scroll of fld "NonScrollingField" to the thumbPosition of me
  end scrollbarDrag

This is completely off the top of my head though, so your mileage may vary.
