Wouldn't it be simple enough to write an app for your phone that would check if it was connected to your "home" wifi and then upload incoming sms messages to your desktop/laptop.

The phone app could wait for you to type a reply on your PC which is then sent back to the phone and then the phone would send it.

I'd be amazed if something like this does not exist.

AirDroid is a pretty good start: https://play.google.com/store/apps/details?id=com.sand.airdr.... It lets you manage most of the phone functionality from your desktop.
