PC could be connected to base station via ethernet cable,
yes, unless you were to add a wireless card or USB
adapter to it instead.
Here's web address about that kit.

Although, I'm not exactly certain what you are asking. If
you only meant connecting the new PC by wire then it's
simple, only needs a networking card already in the
computer and most if not all have one these days. Up to 4
ports in the base station for connecting more computers,
they just need to be configured for networking by joining
a workgroup. The Windows networking wizard should get you
through that okay.
Hope that helps a little.
