How to fetch data from external website (google data api) related to page keywords and display in sidebar

There is a Worpdress plugin, which makes for a great example, that does exactly what I am asking, called Vikispot. However, I would like to use Google Data API as the source of the data for Videos, Blogs, News, etc... then just like Vikispot, display the data on my website in a sidebar. Vikispot does the job开发者_开发知识库 as far as displaying data from other websites that are related to the keywords in a blog on website, in a sidebar. Although I would like the same code that Vikispot is using and implement this into my drupal based website.

I have searched all over the place and cannot find an answer. I hope it isn't right under my nose =]
