Yes it can be that simple. The only issue is whether your
wireless+router+adsl+modem combo box supports it. The usual "port
forwarding" supplied by CPE boxes with off the shelf commercial software
does not work well. OpenWRT and such which allow much deeper admin
control can be configured fairly easily using the Squid wiki configs
like any router.

That is better. But manual configuration can be a hassle on any type of
large or dynamic network.
Interception pushing clients at the squid ERR_CONFIG_* pages help
clients to do it themselves, but can still be trouble.

Slightly more sane is to setup WPAD on the network. Then push clients to
setup "auto-detect". That lets you hide any and all proxy changes behind
a PAC file. Including proxy bypasses etc for the occasional broken websites.

It is much easer to configure with separated wireless, router, and modem

My favourite for this type of installation is:
   clients -> portal (wireless AP -> Squid router -> ADSL modem) ->

With an off the shelf Linux box running Squid and all the regular tools
needed for routing whatever the installation needs its easily extended
or changed. As the AP/modem components burn out or age they can be
replaced without affecting the whole setup.
