Making an OS? That's ambitious. You can either make your own edition of Linux or, you can spend several years making a kernel then spending several more designing and building a GUI.

You need to be a really hardcore programmer of both high and low level programming, who has knowledge of hardware access in great depth.
This is almost impossible task to make a working OS for a single person. It requires team work - experts of various fields.

This pretty much says it all. I, personally, want to be a programmer and know multiple programming languages, but I know for a fact I would not have the patience to make an OS.

However, if you really want to make an OS, you may want to consider helping out the ReactOS team.

You may want to read up on this too: http://en.wikipedia.org/wiki/ReactOS. The main thing I want you to see is the amount of time it took for ReactOS to get this far in development.

Writing your own OS from the metal up is extremely difficult. Doing it well is nigh on impossible!

A somewhat less ambitious project would be building a custom version of an existing OS. You can't do that with Windows or Mac OS (because Microsoft and Apple don't release their source code) but you can build your own version of Linux.

Building your own Linux:

really? It's not as hard as you make it out to be. I recently dicovered how to do it. Just follow these instructions
and improve the code and the GUI, and you'll be set.

I would highly recommend starting off with something like Linux From Scratch. Building an LFS system really isn't hard once you have understanding of Linux. While this technically isn't making your own programming wise, it is a good way to learn the basic principles of what goes on in an OS. Developing a kernel for a custom operating system is no small undertaking. It is a VERY large commitment. If you want to look more into it a good place to start is The OSDev WIKI. As far as those that say that one person can't do it I disagree. While it is extremely difficult to do it yourself and would take an enormous amount of time there are quite a few people that enjoy doing it as a hobby.

I should also add that the most common languages to use for OS Dev are a combination of ASM and C.
