FCP only runs on Apples.
Correction - FCP does not run on Windows.... But it will run on a PC (with Mac OS). They are called Hackintoshs and they are not exactly legal. The biggest problem is that you have to have fairly specific hardware to make everything work. If you are a pro, I would advise you just get a Mac if you want to run FCP. You can also run most of Adobes software on there too.
Does final cut pro works for windows?
Valid question and answered.

So why the question?
Your answer was mostly right. But technically Apple is the Company. They make software, phones, personal entertainment devices. And besides that a person could build or buy a Hackentosh... a computer not built by Apple but running on an Apple OS. A person could create a dual boot PC that would run Windows 7 and Os X. You would have to violate a software agreement to do it but it is possible. I think the real question is... Can I install FCP on my computer? And the answer is maybe... but I wouldn't advise it.
