A URL Pop-up list in a page or post?

I have a number of old artist portfolio pages that I need to link to from a new WordPress page. On our old (pre-WordPress) website, designed in GoLive, the end of each page has a Pop Up URL list with the other archived pages. Here is an example, scroll to the end to see the pop up URL list:

https://store44.com/waynerainey/environmental-portrait/index.html

I’d love to just copy it over, but it seems like it’s a form embedded with some old GoLive code. Just a cut and past doesn’t work. It seems like I’d need to post a fair chunk of javascript in the header to make it work?

The resulting cut-and paste looks the same, but won’t launch a new window. Scroll to the bottom of our test landing page to see what I mean:

https://store44.com/artist-name/

This being WordPress, there is probably a more elegant solution for what I’m trying to do, and I’m looking for suggestions. Thanks in advance!
