The 'treehouse' has a course on it. I did this one (Beginners Guide to RWD) and, honestly, I didn't get that much out of it. It just really wasn't that practical.
The thinkvitamin site all looks nice and pretty but I much prefer www.lynda.com. In saying that, lynda doesn't have so much in the way of newer, cutting edge material. You could try this one (CSS Page Layouts) Haven't got around to doing that one myself but the depth of stuff on lynda is good so if you need some long term tutoring, signing up is worth the $30 a month or whatever it is.
Also, I do know the treehouse has undergone a pretty big makeover (hooking up with CSS-tricks and whatnot) whether it's just a (perhaps Chris Coyier inspired) aesthetic makeover or the courses have got better, I couldn't say as I cancelled my subscription after the disappointing tutorial on responsive web design. I think I only did that one and one other though so it's a pretty small sample size.
Basically though, all you need are media queries in your css to replicate the behaviour of the site that you provided. Then just apply the right css for the right screen width / device... Not sure what you mean by "since all others resize the window" - wouldn't the user be resizing the window not the design? Not sure what you're getting at there...
