Just crate the PCB layout using software like Proteus PCB123 etc
and tale the print on a magazine paper.
and stick the paper on the PCB .
then press by using iron-box a
after put it in to the water finally put it into ferric chloride
this is only the step
you search the Home made PCB on you-tube ,or related video you get the tutorial video
What do you by means by "creating" ?
If refers to design there are a lot of programs ( Kicad / Protel / PADS ) to perfor that.
However if the question is to build the board there are some steps to perform cuper corrosion beyond circuit mask.
