Popup window for register and login

Hi everyone,

I would like to create a popup window for login, logout and register of users for my site. Back of this window will be the page where the user stays. For example, when the user click on login, the popup windows should be opened and after that, the user will stay in the same page as well. I know plugins related to login/logout and register, but I do not know some one with these caracteristics, do you know any one?
Thanks in advance.
