Creating a website for a final project, need massive help with action script!

Ok so my website is a basic portfolio site. the interface is as follows: on the right is a box shape...to the left are my buttons and on the top is my logo and such

now for my coding questions.

1. I want a gallery to appear in the box showing my work

2. My buttons are named "Photoshop", "Illustrator", and "Indesign", i would like to have it so when you click on each button a new window gallery will appear in the box to show my work for each pogram

3. How do i insert my images? Do i just place them in my library in Flash? Do i use dreamweaver?

thats pretty much it.Unfortunately my teacher is refusing to teach coding so i need all the help i can get lol

Thank you
