Login to see content

I am creating a wordpress site as a CMS system, so no blogging only pages.

I want wordpress to go straight to the home page and have the login prompts on the home page. I don’t want people to be able to see any menu options or info, only the welcome/home page and the login.

Once logged in they can see the content etc.

Any suggestions, I have played with about 20 add ons without success.

Thanks!
