Someone on the Joel forum recently lamented the lack of decent prebuilt web app templates:

I quite agree. Open Designs: http://www.opendesigns.org/ has bazillions of blog and corporate designs, so I don't think it's entirely unreasonable to expect a few more web app templates would be collected somewhere.

I suppose I should be the first to mention Weebly: http://www.weebly.com/ I've used it to bang up a quick UI and it's fine if you can accept its current limitations.

weebly and open design are both awesome, ty very much, exactly what i wanted.

Emacs. By the way, you ought to attempt to improve your writing as well - it's painful to read something with a nearly total lack of punctuation and proper capitalization.

Just because its the 'internets' doesn't mean that good grammar/spelling/etc. are not appreciated. The more clearly you communicate the likelier you are to get some help.

As for your initial question, perhaps something like Dreamweaver - http://www.adobe.com/products/dreamweaver/ - would be what you're looking for.
