import c++ file(that opens in cmd)
What do you have? Source file, object file, compiled executable?

source file and compiled executable

source file
If you have sources, it is simple. Just add them to your program project and use other program features like it was a simple library.

#include <iostream>

using namespace std;

int main()
{
   float x,y;

   cout << "Enter an event/s" << endl;
   cin >> x;
   cout << "Enter a number of outcomes" << endl;
   cin >> y;
   float a = x / y;
   float b = a * 100;

   cout << "probability is " << b << "%" << endl;

   system("pause");

   return 0;
}

woah!! im just gonna stay away from GUI.

Heh!

You should start small with a GUI library like Qt (http://qt-project.org) which is compatable with C++. See the examples and tutorials to get started.

After you figure out the basics of GUI programming in C++ you can graduate to using pure Windows API calls.

That's exactly what I said when trying to start with c++ GUI.
