Now this is what I call a collection of masterpieces in one place. I have used the Zoho creater, it is one piece of application which can be used by anyone, anyone who even does not have any knowledge for HTML or database. This helps create an awesome form which could be connected to a database. This is useful for just creating mockups of screens, if you want to make a prototype.

Some apps are free and some come at a cost, still worth all the bucks.

Web applications and steroids, nowhere to go wrong.
