Theme development

I am trying to create something that is most likely simple but giving me a hard time. I want to create a page that has at the bottom a grid of video thumbnails. When you click on any of the video thumbnails the actual video appears in a player at the top of the page. So think of it as a news site. When the site loads.

Underneath the player are other news items that once you click replaces the featured story at the top of page and plays video.
