The simple answer is that you can not do this. The best you can do if 
you want to use Google maps is to use something like OpenLayers or 
Geomoose to display the Google maps as a base layer and base layers MUST 
be in the projection of the base layer, ie: Spherical Mercator. Then use 
mapserver to reproject your data into Spherical Mercator and overlay 
that as another layer over the Google maps layer.
