Huh? Did you install the AirPort Base Station, an AirPort Express, or the AirPort software?
You can safely leave the AirPort software on your machine even if you don't have a wireless network. It takes up a small amount of space and doesn't interfere with normal operation. I don't have a wireless network, and I have the AirPort software installed and it doesn't cause any problems over here...
...perhaps I'm not understanding your question correctly -- can you elaborate?
