Get command/event from a local website, using c [closed]

In my current project it is necessary that I send commands to a running C program via a local (Apache) website. I have various buttons on the website, as soon as one is pressed, the C program should execute action X. It doesn't matter whether it's sent through a native interface, through an event, or through sockets. At the moment I just have no idea what is the best way to implement this. I would prefer an implementation with Javascript-to-C, but if there is no other way, then I will also work into something else.

Thanks for your help!
