Can I create a single view that contains fields from multiple tables?

What do you want that "view" to be?   A form?   A report?

From the form perspective, you could add "views" and "subtables" as well as use formula fields to DISPLAY fields from multiple tables.   To update those fields, you would either click through to the base table to update it.. or write logic behind buttons / after update triggers (etc) to update the other tables. 

Hope that helps.
