Web Site using QlikView technology but without using WorkBench or html with QV Plugin !?!
What do you mean? AJAX is one of the 3 built-in web clients in QVS...in your AccessPoint you should be able to open your application in AJAX, Java, or IE Plugin (assuming you didn't disable any of these). Also, if you go to the demo site (http://demo.qlik.com/) they've created a bunch of AJAX examples here. For more on the AJAX client, see the Qvs Reference Manual.
Once you verify that your application is served well in AJAX, you can simply put it into an IFrame and design the rest of your site however you want. If you need to implement some security, the simplest option is Section Access. which will prompt the user for a login inside the IFrame. If you need something more advanced then ticketing (SSO) solutions can be developed as well.
