project – How to make a flowchart to code generator

this is my first question ever on stackoverflow and i am kind of a newbie here and in programming too so please excuse me if i make any mistakes.
Okay so my question is i want to make a project on to convert a flowchart of an algorithm into a working code in a few programing languages (for ex, c,c++,java,python etc). Something like what flowgorithm does in a nutshell. If i want to make something similar like that, how must i proceed?
