Usually, if you did not have 'Skype' then the alternative would be 'Windows Live Messenger' if you have a web cam and a mic. then this should work out fine if you both use messenger and accept the invite.
That question is like, 'Can you water ski in Michigan if you live in California?' One has nothing to do with the other. To video chat with SKYPE, you have to have SKYPE and a webcam attached to your computer, and and Internet connection. SKYPE does not video chat with MSN nor other chat clients.

Apple made "FaceTime" for video calling from MAC to iPad 2, iPhone 4, iPod touch or MAC. All you need is an Apple ID and an e-mail address and that's it! Another way for video chat is "Yahoo Messenger 2.0". With yahoo messenger 2.0 you can make voice+video calls to other messenger users on iPhone 3GS, iPhone 4, MAC or other windows running systems.
If you're talking about windows live messenger then yes you just need a video camera and connect it to the computer - there are some laptops that already have a camera in them - and a microphone, connect the microphone right next to where you connect the headphones.
