Unless you find a free host, you have to purchase hosting as well. Since you dont have much clue on what to do, stay close to this forum, and post questions. You will find several of us eager to help you along.
You should shop round and get recommendations for your hosting. I suggest www.serverme.com. Then you should use a scripting program as you don't have any experience yourself. Use something like Microsoft Frontpage (simple) or Macromedia Dreamweaver (more advanced)
