If you have an ikea near by, they have their wireless charger for $12 and it can be used as a stand alone charger or can be flush mounted (as long as you don’t mind drilling into your desk). More on reddit.com

The biggest problem is charging your iPhone and Watch. They use different charging standards, so you can't use them interchangeably. There are some offerings from companies like Belkin (some even advertised on the Apple Website if I'm not mistaken) that act like a multi-function dock. One cable, but can charge both your iPhone via MagSafe, and your Apple Watch via it's charger. New AirPods Pro can be charged with the Watch charger, like you've said. So theoretically, this would solve your request.

Honestly, $130 for a charger is wild. It’s nice, yeah, but you’re mostly paying for the Belkin name and aesthetics. I grabbed a 3in1 wireless charger off Amazon for a fraction of that - charges my iPhone, Watch, and AirPods just fine, no issues with speed or heating. Unless you really care about matching Apple’s design vibe, you can save a lot and get the same performance. More on reddit.com

This sounds very similar to the AirPower project that Apple supposedly canceled because of heat dissipation. You may have trouble finding such a thing. More on reddit.com
