Can an airport express be used to add wireless to a PC with the ethernet cable? I have an existing wireless network and I want to use the airport express rather than a usb adapter to add wireless to my PC to join the network, is this possible?

Yes, you can definitely use an airport express for that purpose: you set it to join a wireless network and then set the checkbox to allow Ethernet clients.
You can then plug your computer into the Ethernet port and it should work fine.
