Sometimes I really have to wonder about your questions. You state that you have learned Fortran, Visual Basic, C# and C++. Then you ask if every software is written in C or C++. Man, you yourself have already written software in other languages than C or C++, so you should know.

Why Linux OS does not have something like Visual Studio?
Eclipse (many languages), Netbeans (Java), Monodevelop (C#), Code::Blocks (C++), and many others for different languages.
OpenOffice.org at least is written in Java. And a fair number of GUI applications that I use were written in Python, to give you some specific examples.
I am just curious,
I always feel regret that I did not study Computer Science.
Those scripts in a programming language, determined by whom?
Like:
printf
writeline
etc..
Ok, let's say Visual Basic can be used to write a software, maybe a simple game, Visual Basic is the Creator of this game,
my question is, What created Visual Basic?
This is like the theological question, God created men, and we would ask "Who created God"
I might be funny to ask such a question.
But I really want to know how software was created?
I know that the very basic is Machine Language, right?

That's a great question. Back in the day, the first computers were programmed in machine language - just using the instructions that the computer used. Two of the early computer languages to improve that took radically different approaches:
FORTRAN was aimed at mathematicians, so it allowed familiar variable and formula notation.
Lisp was aimed at computer scientists interested in theory of computation so it used a functional notation.
When the Bell Labs guys wanted to write a new OS (UNIX) they decided they needed a system programming language, C, which gave them all the capabilities of machine language but a higher level of abstraction. The Linux kernel is also written in C.
