Is it possible to send button click signal to qt side without forms?#32

Hello, I want to implement multiple buttons on one page for ex. to control blind rollers, by pressing a button the blind goes up by few centimeters, by press and hold it continously goes up etc. Is it possible to do this mechanic using this library? I only saw examples by sending data using forms and post/get method but can you use javascript to send data directly to c++? or plain input type button without the need of form? Thanks for response :)
