The application uses Visual Programming Languages. There are many projects in this domain, but most of these languages are domain-specific languages that are used in education, But with respect to general-purpose visual programming languages, there are few of them. PWCT don't use the Drag-and-Drop method. PWCT provide a new method based on Automatic Steps Tree Generation and Update in response to interaction with components that provide to the user simple data entry forms. The idea behind this new method is to mix between programming using Diagrammatic approach and programming using Form-based approach where the integration between the two approaches are done seamlessly through an Automatic Visual Representation Generation process. This is just the basic idea and many other ideas are developed around this concept to get a practical general purpose visual programming language for real world tasks.
