My first application in Dlang

[Marcone]

Hello, my name is Marcone, I live in Brazil, and I have been 
studying Dlang for a year. I finished my first application in 
Dlang with a graphical interface in Win32api and made it 
available on the internet for anyone who wants to download it. 
Here is the program link. As a beginner in the D programming 
language, I would like a note from you who have been D 
programmers for a long time if I am doing well. What did you 
think about the application?

Thank you.
