So... how do I write a KDE4 widget using python ?

[linuxguy123 at gmail.com (Linuxguy123)]

I'd like to make a simple scrolling "banner" widget for my KDE4
desktop.  

I've read little blurbs about how KDE4 is now supposed to allow users to
write their own widgets easily using Python.  So how do I do it ?  Where
do I start ?

I know about python and pyQt. But how does one make it a widget ?  Is
there a tutorial somewhere ?

A few more questions... 

I'd like my banner to be frameless.  Just scrolling text on my desktop.
It shouldn't doc in the taskbar. And I'd like it to handle right click
events.

Is this possible ?  

Thanks
