Yes. All this can be done in Dreamweaver.
First create a demo [skeleton] HTML page.
With the basic header, footer and sample main content.
Then create "editable regions". (Insert -> Template Objects -> Editable Region)
mark only that regions which will change in individual pages.
Save it as a HTML template.
The next time you create a HTML page, use this template to create. There would be an option by the name "Update page when template changes". Make sure it's checked.
Now whenever you would update the base template, it would ask you when saving "Update all files based on this template?". Click on the 'Update' button there, to update all the pages accordingly, autmatically.
