Keyboard/Mouse alternative for Gaming TV + PC setup?

I have my TV hooked up with my PC and I want to use it from the couch. Currently I have to use a wireless mouse and keyboard which is not comfortable on a couch setup as you can imagine, also I mainly use it for gaming so I have to manage Keyboard Mouse and Xbox Controller to be able to get a complete experience.

Is there a solution where I can connect a keyboard attachment with the controller and use the sticks as a mouse?
