That seems like it should work.  I don't see why this needs to be any
more complicated than just refiling the messages to a local maildir.
However, if you don't trust elmo to refile messages ...

Assuming that "Gmail label" maps onto an IMAP folder, it sounds like you
basically want to mirror an IMAP "folder" to a local Maildir.  This is
exactly what offlineimap is for, and it works very reliably [1].  I'd
probably try that before any trusting solution that required wine.
