I'm not sure if it can be both an access point and a Web server at the same time... If it can, just create a Web server as many examples show: a Web server on a connection connected to a Wifi network with the SSID (and password) for which you just created the access point. About the ip addresses or url to ip address resolution with that setup, I have no experience (yet).
