Is dry-run of WordPress without web host possible?

Is it possible to run WordPress on my own computer without any webhost just so I can see a mock-up of what my site would look like?

I mean so the entire thing is on my local hard drive. I am NOT talking about hosting a website from my hard drive. I only want a mockup so I can see what the layout of text and photos would look like.

Then if it looks okay I would proceed with actually setting up my site normally with a web host.

I do NOT need functional comments or widgets or anything like that.
