WordPress Login Form

Hi

I am trying to add the default login form using the optin popup for a client of mine.

The way I am planning to do is use he popup on the site as soon as the customer enters this will display the login form. This login form will be for registering as well as logging into the site.

Once this task is complete the person should go to the redirect page. Also I want that the vistors only choice is to either register and proceed or go back from the site.

Is this option possible with this popup

Thank you
