How Do I Throw a Baby Shower?

I am not too sure how I would go about with planning my baby shower. To make things mor complicated my boyfriend and my family don't get a long very well to the point where they can't be in the same room as each other. I am not too sure what to do. I am just curious of ideas and how I would be able to do this on a cheap budget. If you have any suggestions please help me? I am desperate.
