Do I need a desktop to setup wifi

I bought two iPads and want to set up wifi in my home without a desktop. Will the iPads recognize any router I plug into
My cable modem? I have an airport express as well but wasn't sure it would be strong enough for my entire home.
Both routers have setup CDs but I don't have a desktop? I was hoping I could just plug a router in the wall, connect the Ethernet cable to it via the cable modem and have wifi. Will that work?
