Winlogon.exe is the first UI process that is started and reacts on Ctrl+Alt+Del. Because it is the first process, it sees all key events first. So to hook up before that process you need a kernel-mode driver. No other chance. Take a look at

http://www.sysinternals.com/ctrl2cap.htm

for an example. Unfortunately, the sources are in C and you need the MS DDK to compile them.
Note that you are going very deep into the OS Kernel with that, this is not very suitable if it isn't absolutely necessary.
