Surplus PC with an extra NIC and OpenBSD.

Edit: oops sorry you wanted a GUI. I'm guessing there are some GUI tools for pf around but I don't know of any.

The de-facto standard packet logging and tracing UI is wireshark, so if you're going to go the surplus PC route then run wireshark on it. I have no idea if it's available for OpenBSD but it's certainly available for linux and windows.
