Wifi stemma qt module?

I have a micropad, I was wondering if there is a way using the stemma qt port to hook up a wifi module?

Not that I am aware of; I have not seen I2C WiFi modules. For a wifi module you'll need access to the SPI bus and a handful of digital GPIO pins for control signals (3 is usually enough).

The Macropad's SPI bus is internally connected to the OLED display, I'm not sure if you'd be able to use it for something like connecting an Adafruit AirLift wifi module

That's what I'm going to look at. Getting MOSI/MISO/SCLK from the display connection should be straight forward, although delicate, bodging. The trick will be picking up a few lines for the AirLift SPI control pins.
