can i edit an existing web site with an asp.net web application?

i have a resume web site that isnt very good, and is unfinished. i want to add to the main page by just adding controls to it with visual studio. but i cant figure out how to get my page in the VS gui. i know in a windows form application you can add the web browser control which allows you to type in a url and that site loads up when the program is run...is there something like that in an asp application?

thanks for any help!
the site was written in html only
