I really like the branded widgets on the right side of this page for Twitter, flickr, etc: http://truelecreuset.com/community/

And I'd like to put them on a page like this on this site:

I would need to add the widgets via OpenCMS on the front end, and since the site I want to add them to is Java based, I've been told I can't use PHP. Is that true?

I've looked at the source code for the blog, and even the dashboard to try to figure out how they are doing the widgets and I can't break it down on my own. Any help?

The basic widgets available through Twitter and Facebook don't offer the level of customization I'm looking for. Flickr is taken care of.
