The uploading part is taken care of with timsieved, which implements their 
"managesieve" protocol.  I wrote a kioslave for it, which I still have if 
anyone would like it. I also remember seeing something similar in kdenonbeta, 
though at a glance I can't see it right now.

To me the time consuming part is writing the gui to create the sieve scripts 
in the first place.

Do you have numbers to back that up?  From appearances, sieve seems designed 
to handle this load... "The language is not Turing-complete: it provides no 
way to write a loop or a function and variables are not provided."  With only 
the particularly savvy users likely to write very complicated scripts, I'm 
pretty certain you'd be in the clear.
