hope this is the right place, stuff about pages

Hey I’ve been using wordpress for a while now on two of my sites and now I’m working on a site for a friend of mine.

What I what to be able to do is create my own page file but have it show up on his blog like a post or a page would.

Is there anyway I could make this happen? Thanks
