It sure is possible. If you are working in low frequency (kHz not MHz) just a couple wires will do the job. For years I had an old HP 1 MHz bandwidth scope. It didn't even have BNC (shielded) inputs just banana jacks so it was intended just to use simple wire leads.

Pretzels is right, but note that he is keeping the frequency low. As you get up in speed, it becomes more important that the probe be "electrically correct" as to its impedance and circuit loading. A home-made probe can change the behavior of the circuit you are trying to observe. In high speed pulse work (like computer logic) you can get all sorts of wonderful reflections if you don't watch out for probe characteristics. Decent probes can be had for a few dollars, so if you are going to do a lot of it, part with some cash.
