I think you really need a proper GIS to preview whether your mapfile
returns what you need, so I think the qgis approach is a winning one.
Please note that the current approach is light and fast, as it is based
on a standalone tool in python (so easy to maintain and change as
mapfile syntax changes) who takes a qgis project and converts it in a
mapfile.
I think in the long term a nicer approach would be to use a standard
description for both qgis and mapserver (possibly other projects also),
with additional tags used for desktop gis and invisible to mapserver, so
no conversions would be necessary. SLD might be a good approach in this
sense.
All the best.
