Yup, that's exactly what OP wants. You write some software to fetch the calendar / org-mode entries, and there's your prototype for the Kickstarter. Like all hardware projects, the tough part is the software and the marketing. The software honestly feels like a day's worth of work. I don't know if TinyGo has a driver for the Pico W wifi chip, but I've used an ESP32 with nina and you basically initialize the WiFi core and then use net/http like a program running on a big computer. Very very easy. Times have never been better for Internet-connected microcontroller programmers.
