Hot to show system resources on Active Desktop?

Hello!!
At the beginning I'd like to apologize for posting on group that doesn't fit
this subject, but I haven't found any that would fit it.
I am looking for informations, hints or source codes about how to display
system resources
(cpu load, mem usage...) on active desktop.
I know that I need to use WMI for it and I have found documentation about
the WMI on MSDN with WScript example that shows cpu load, but I don't know
how to put those informations on a web page (active desktop) and refresh
them continuously.
Could anybody help me?

Best regards,
Marcin
