I need help with planning my graduation party!!!?

I wanted to have sorta a Willy Wonka themed graduation party. But not really willy wonka I want a lot of dessert and candy and everything. I also want some regular food. I need some good ideas. Also I want my party to be memorable. I want to have like a dance party or something for my friends later at night. Any suggestions for that too. I also want a creative idea for a guest book. And also any other cool ideas that you have seen or used would be so helpful.
