Starting with D2000 - I want to create my first application

Hello
I am beginner with D2000 system. I downloaded D2000 V12 for Windows from D2000.ipesoft.com, I installed it, but now I don’t know, what I have to do for my first application. I would like create some visualization, without communication, only small application for beginners, … something as “Hello World!” But… I don’t know what I have to start as first. D2000 is installed and EXE files are in D2000_EXE folder. But there is many programs as Archiv.exe, Event.exe, Kernel.exe, HI.exe, GR.exe, CNF.exe, D2SMC.exe … but I don’t know what I have to use for this application. When I checked windows services after installation D2000, service D2000 Kernel is running, but I don’t know if I necessary it for my small visualization. Has anybody experience with this SW? Can you explain me, what is the best way for creating of first small application?
Thanx

Hello
If the application is in running state (process D2000 Kernel running) you can use D2000 GrEdit for creating and manage you visual forms.

For to visualize you forms use D2000 HI.
