You know, libpcap exists for a reason: It does something that's necessary.

You need to set up a system-level hook for TCP/IP events, and the way global hooks work means you need to do this from a DLL.

Having hooked those events, you have to figure out the contents of the packets you get.

Are you sure you want to re-invent this wheel?

I found some introductory info on hooking Windows events here.

You could start to do kernel level programming and catch there the packets. This is for sure complicated but you'll learn much.
