Its possible, I used to do something very similar with one of my RPi's when I first got it. I had a situation where there was free (although limited) wired internet, but no wireless. I had the PI configured to fire up an OpenVPN client initially connecting out through the Ethernet port, then create a wireless accesspoint complete with DHCP etc for the WiFi clients.
Final piece of the jigsaw was to use iptables to NAT the WiFi DHCP addresses behind the tunnel interface created by the OpenVPN client.
If I still have an old SD card image kicking around, I'll take a look to see if there is anything helpful on there. I would start with getting the WiFi working, with your own DHCP server and perhaps DNSMASQ with IPtables. There are lots of pages with how-to information for that. Then get the VPN working (in isolation initially), again following the many howto's. It should then be quiet simple to get them to work together by making sure the VPN is up and changing the iptables NAT rule.
HTH.
