APEX

After a successful login, is it possible to run the application through a POPUP, so that the back button etc are not displayed. I want the entire application to run as if it is from a popup URL, when the logout is pressed, then close the application and go back to the welcome screen. Is this possible, and if yes, where do I specify this. At the post-authentication process or login process ?

Second option i want to try is after the login is successful, run the entire application using a IFRAME in a separate frame so that the changes in the URL are all not displayed.., is this possible, if so, how do I set this up ?

Want to try both these options just out of interest to check security through obscurity..;
