The instructions that you mention all assume that you have installed AirPort Utility on your PC. is that the case?
AirPort Utilty 5.6.1 for Mac and 5.6.1 are virtually the same so instrucitons and illustrations for Mac should track closely, if not identically to the Windows version.

Yes. I have the airport utility for windows v. 5.4.1 installed on my computer. I have enabled guest networking and file sharing.

I'm not sure if the 5.4.1 version that you have will do what you want. Did you mean to say that you had installed the 5.6.1 version?
Sorry, I do not have a PC here handy to test, so you will need to wait for another PC user who can give you step by step instructions.
