How to restrict Web part editing on a page

Hi ,

I have a few web parts that display information on a home page. I want to restrict editing of the web parts. That means, All users can see the web parts but only few users (say that belong to a group) only can edit or change the Content of the Web Part. This should be the case for few other web parts on the home page. I am not sure if this is achieved OOTB or not. I have no privilege of coding in SPD or VS.

Thanks,
