There is a thread on gnus.emacs.vm.info about the same question in
VM-land.  First, you will need a script to turn mswordview into a real 
filter.  This is what Kyle Jones wrote:

#!/bin/sh

trap 0 "rm -f /tmp/$$"
cat > /tmp/$$
mswordview /tmp/$$

Then, you need to hook it up the Gnus.  This is how you do in in VM,
and I imagine that Gnus has similar variables.
