We are trying to migrate from Universal Analytics to GA4. The issue we are having is that GA4 requires a client_id field which we cannot get in a desktop application (C++). Is it possible to get client_id without a browser? and without being an IOS or Android app?

Just generate a unique id for each user, that's it. That's exactly what GA does on web. Same applies for GUA. I wonder how you were tracking users without setting client id for UA. Were you tracking them?
Another thing is that despite all the fuss around GA4, it is an unfinished product. Even though Google recommends it, the professionals who actually work with GA's data recommend to either not use it and give it another year or two or implement it very shallowly in parallel with existing tracking just to have some semblance of historical data in it when it's time to switch.
Finally, if you're tracking a desktop app, you likely use the measurement protocol rather directly, so you mind find this useful: https://firebase.google.com/codelabs/firebase_mp#2
