I want to make a simple webpage. 2 textbox and 2 button. This webpage will be like a login:

Username (txtbox1)
Password (txtbox2)
Login (but1)
Reconect (but2)

This login connect with this flash game: BoomBang: Chat & Play and tell me if is correct or no.
But i don't know how to make webpages :l (only a little Dreamweaver)

Somebody can send me tutorials, or tell me the lenguaje that i have to use, how to make the connection..

Thanks a lot, and sorry for my english.
