Which plugin would give similar results

I am trying to build a lead generation site and I found a site built in PHP and I really like how they built out their sidebar and I am looking to do this same thing but in wordpress.

I don’t know much about programming or anything so I can’t custom build it but I am wondering if there is a plugin / widget for the sidebar to give the same result as what’s shown on the following website:

Help would be greatly appreciated.
If there is any simple coding I could put in there to build out that box I would appreciate that too.

Thanks
