One of the most popular tools for Rapid Prototyping is Visual Basic (VB).
Microsoft Access, which includes a Visual Basic extensibility module, is also a
widely accepted prototyping tool that is used by many non-technical business
analysts. Although VB is a programming language it has many features that
facilitate using it to create prototypes, including:
An interactive/visual user interface design tool.
Easy connection of user interface components to underlying functional
behavior.
Easy to learn and use implementation language (i.e. Basic).
Modifications to the resulting software are easy to perform.
