Hi, Wajeeh. Do you have a router (1/2" collet minimum) and a lot of expensive bits? Do you plan to build another door? If you can't answer yes to both of these, it will be cheaper to buy the door. A good 10" table saw is a must too. This is not a good beginner project. Remember that you will be buying some expensive wood and polycarbonate. Most building codes specify polycarbonate or tempered or safety glass for doors so check your local code.
