Writing UNIX-like ps for WinNT?

Hi!

I'm wondering how to write an executable that snapshots and lists all
active processes
and prints their PIDs, names and CPU times in a console window, rather
like the "ps"
command in UNIX. (Or like the list displayed in the TaskManager in NT).
Something like this:
>ps
PID   CPU    Name
123     12%    someservice.exe
231     1%      notepad.exe

I suppose one could loop for(PID=0;PID<1000;PID++), do a OpenProcess()
on every
possible PID, and if a handle is recieved, print out the PID.
But how can I find out the name of a process with a certain PID?
How can I get the processes current CPU usage?

I would also like to write a "kill"-command, that could terminate a
process given its
PID. The latter is probably easier, just do a OpenProcess(), and then
Terminate()?
(Ugly, but still...)

Maybe someone or some company allready has these commands available for
NT?
Code examples?
