I think it's possible to do it, tho I haven't looked into it lately.
Waaaay back in the days before cable modem routers were commonly available, I ran IPNetRouter to make a virtual interface, permitting me to use a Mac as a router and NAT server without requiring a second Ethernet port. It might be possible to do the same thing on a modern Mac with WiFi.
The first AirPort Base Station (Graphite) could also do this too. However, it caused problems because the second network was not really behind a firewall, and could screw up others on the network it was attached to.
A wireless card could in theory switch channels and connection settings for the second network, but as I mentioned above, there would be some overhead in doing this which would likely slow things down a lot.
