I assume the ip address 71.228.29.37
is your routers WAN ip address.
In that case you are getting GoDaddies DNS to point to your ipaddress and you need to Port Forard your router to allow connections made to this ip address to be forwarded from the routers port 80 to the internal PC's ip address's port 80 and therefore to Apache.
See this site http://portforward.com/ for help in setting up port forwarding on your particular router.
Also make sure that your PC running WAMPServer is setup with a static ip address.
