Practice without a Web host?

Hi,

I’m starting a small business and I’m looking into building my own Website with WordPress. I won’t launch the business for several months and I don’t have much of a budget, so I’d rather not pay for hosting services until I start offering my services. However, I want to experiment with WordPress now, so the Website can be ready when the time comes.

Is there a way to design your Website without a Web host (i.e. offline)? It doesn’t really matter to me if I have to do everything all over again once I do get a host. I just want to learn how to build the Website that I’ll want to use (design my themes, etc.).
