Yes it can, but that would be a lot of work. GeoServer (based on GeoTools) does this out of the box and with the right image generation setting you won't regret the switch from MapServer (GeoServer defaults on good image quality, you'll have to work a little on the request parameters to get the lower quality but faster responses that MapServer provides out of the box). Coupled with MapBuilder or OpenLayers you should get everything you need.
