The wireless network can be treated as if they had an ethernet wired
connection.  You need a DHCP server.  You will also need a DNS server
(or a fake DNS server) that points to the device.

DNS is complex, but you can make a fake server by answering any DNS
request with your device's IP address.  This should be very simple,
and will make it so any computer attached to the network will access
your device regardless of the website it tries to access.

A DHCP server should be similarly simple - a little more complex to
handle the case of more than one computer attaching at once, and
perhaps tracking IP address leases, but you could dumb it down further
with some assumptions.
