Uhm. Uhhhhhhhm. I ... uhm. I can't compute a bezier point out of x/y coordinates. Hm. I could calculate new points between the two closest points. To be honest ... I never thought about doing it that way. Thanks.

You might need to use some complicated math to break apart your curve into smaller "straight lines" to attempt to get the right locations.

Yes. That's true. But those problems are already solved. Actually I'm doing some math to place the buttons not just in fixed intervals. I didn't mentioned it below to keep the my description as simple as possible.
The button shape is transformed according to the buttons position and angle. So the buttons never hit/overlap each other. Like with the second and third bar in the screenshot below.
At least something that is working as expected.
