For such low frequencies, you can simply breadboard the circuit to test it. There's not much to go wrong with a simple buffered PWM output and buffered low pass filter anyways.

For the network interface, maybe it would be easier to just put in a "TTL" level (unbuffered) UART header to hook up to something like an OpenWRT router to handle the actual network interfacing.
