Certainly doable, but it really looks like the unnecessary hard way to do it.
If you set up openvpn somewhere you can just handout .ovpn files and tell your relatives to install the openvpn client on windows. Then they just have to double-click the .ovpn file and iconise "that black window that appears" (the DOS prompt window).
