Lazarus (delphi alternative)

Hi all!
First of all - sorry for my bad english.
I tried to look for similar topic but found none.
Liked the project haiku. I would like to participate in something like the life and development of the system. But I am very sad because I can not find the Lazarus delphi or other alternatives. Where once heard that there is a version of Lazarus and it works. Help me find it. And very much like a precompiled version.
PS: I agree that C - good programming language but now it's not my choice.
Best wishes.
