Facing much difficulty

I never knew making a website was so difficult. There are so many webpage that I have to create and design. This is giving me a headache. I have to do a web application project by making a website about a certain topic.Mine is about airline reservation.Not to worry, this website I am making is not real though in the future,I might just be making a real one. The first part is about database. Making the database is very easy but the second part is the layout of the webpage and it's design. That is not the hardpart yet. The hardest part of making the website is to make it function. Function such as submitting data and creating a profile is mind boggling even though I have a knowledge of Dreamweaver. Still, you can't go through a journey without an obstacle. I have to submit this project by the end of next week. It's a ridiculously short time limit for a person to create one big website. Fortunately, this project is not an individual work.I got a friend to help out with the webpage designs.
