OpenVPN has a nice unobtrusive openvpnGUI client you can distribte to your Windows users, along with the appropriate PKI keys. The specifics of how you want to do your PKI key management are left up to the system administrator as an exercise, but it uses OpenSSL keys, so anyone familiar with those should have no problems.
