create a page

Hello Friends,
Can anybody tell me how i can create a page, like MS-WORD,
using javascript.

I have an IFRAME, inside which iam inserting an div, which makes you feel like page, but as soon as user fills tht page by writing over it, another div should come automatically, below this first div.

Can anyone help me out. Iam creating an application like MS-WORD over net, i made it everything (bold,italic,underline,alignment,spellcheck,table properties,image, file insert, special character,File Menubar, Toolbar,Statusbar) Just i am hanging out only for page setup properties.

I will thankful if some one help me out.
