Is it possible to have an Iframe that loads a separate browser window into an existing webpage?

I need to build an page that has an ifame (not sure if this is correct) that will load another browse-able website within the page. The base website will act as site that asks questions about another site and the user will have to browser the loaded site to find the answers. Is this possible?

Please view the reference for a visual.

Any help / tutorials would be great. Overall I'm just not sure if you can browse a site within a current site.
