in its most simple form you could script in a button

local sTurning = false

on mouseUp 
   if sTurning = false then
      put true into sTurning
      put "This is Bills text" into tText
      set the displayText of widget "turnText" to tText 

      -- turnText it is a property, you script "set the <property> to value 
      set the turnText of widget "turnText" to true  
      put false into sTurning
      set the turnText of widget "turnText" to false
   end if
end mouseUp 

if that is what you want. It just turns the text until you click on the
button again.
While it is turning you can change other properties like text or speed or
textSize using different buttons. Look at the code of the sliders.

If you wanted it to turn by setting the angle I could give you a different

Kind regards
