PWCT is not a Wizard for creating your application in 1 2 3 steps. PWCT is a general-purpose visual programming tool designed for novice and expert programmers.
A novice programmer can use PWCT to learn programming concepts like Data Structure, Control Structure, Programming Paradigm,..etc.
An expert programmer can use PWCT to develop large and/or complex software.
Using PWCT we developed a textual programming language Compiler and Virtual Machine, This language called Supernova (http://sourceforge.net/projects/supernova). Another projects developed using PWCT are the Smart POS System (http://sourceforge.net/projects/pos-sys/) and the Critical Nodes Application (http://sourceforge.net/projects/criticalnodes/).
You can see/edit the generated source code. PWCT support Harbour, Supernova, C, Python, & C#.NET and you can extend PWCT to support code generation in any text based programming language.
PWCT comes with many samples, tutorials & movies.
