Fitting a Vocal booth door on drywall/plasterboard PLZ HELP

Hi all, I'm currently making plans for a cheapo, vocal booth... priority is not isolation but is the acoustics (like I said, cheepo :-) ) Im making the booth from a stud timber frame, drywall sheets, and rocksilk fiberglass and acoustic material. I want to get a medium weight door... but I dont really have any idea how you fit a door. I am quick to learner.. does anyone know where I can find some guides? I'v tried youtube but cant find what I am after. I take it I need to: Cut a door shape hole out of my plasterboard then make a stud timber frame around the door hole (which the plasterboard will be skrewed to). build out where I want the door to close to. Can I then simply hang the door on the frame work with hinges?? I will be using a seal on the door etc,, but my main concern is how to actually hang it,, and if my method seems ok for a DIY CHEAPO vocal booth?? :-) Hope someone can give me some DIY pointers? Cheers

ACCURATE DOOR FRAMING FOR PREHUNG INTERIOR DOOR This is a fairly good video on framing for an interior door with no ceiling load. Somethings may have to be reinforced, like the size of the material.
