how to create home page for the application?

hi there,

I had gone through some of the applications available in market place. I would like to know how to create a home page, i.e. the page which the user will visit first when he wants to use the application.

Further, how can i put important links on each page which may differ on each page to navigate the user to different forms in the application.

thanks in advance
