You'll want a Wifi Router. It will have the wired ports for you to connect the PC.
Apples can use Wifi just like any other systems.

i apologize in advance for what is probably a duplicated question, but i can't find an easy answer. i would like to connect my new ibook(with airport extreme card) to my home cable internet connection via a wireless connection. i'd be happy keeping my pc wired to my cable connection. i'm mostly interested in internet access from both computers and not all that concerned with sharing files between the computers. what equipment do i need and how do i set it up? thanks.
