Porting them would be an option

Sure there is a way to build this (for Python): build it yourself using the Windows 7 API’s.

It is a pitty the Q7Goodies you linked to are non-free software (and one of the demo’s crashes immediately on startup), even though at the top it states “Download now, it’s free!”.

Well, I guess they mean “free” in the money sense, not the liberty…
Anyway, porting this one, another one, or even building it from scratch in Qt or Python, I was just wondering if someone already did it.

Unfortunately, I don’t have the necessary knowledge to do it by myself…
But I hope it will be possible in PySide one day!

Not even that. It is just a 30 day limited demo.

Edit: Off topic:
I don’t like Windows 7’ taskbar at all. I find it very confusing what is a running application and what is a button that will start one, and I find the lack of text next to it annoying.

We provide PyQt bindings to Q7Goodies too. If you are developing a commercial application and don’t mind buying a library then probably PyQ7Goodies is the easiest way to go.
