Replacing WinMain() with main() function in Win32 programs

I searched a little bit on StackOverflow and Google but couldn't get the idea. I want to start my application with this type of user programming:

int main()
{
  Window App("Test", 640, 480);

  while(App.IsOpen())
  {
    // Do the stuff
  }
}

But this isn't possible because I should pass the hInstance and hPrevInstance and other parameters to a WinMain function. Actually there is a Window class which I designed to make the window creation a little bit easier. I saw this implementation on SFML but I don't know how it did come to this.

Right now I'm using the usual way:

int WINAPI WinMain(HINSTANCE hInst, HINSTANCE hPrevInst, LPSTR, int)
{
  Window App(hInst, hPrevInst, "Test", 640, 480);

  while(App.IsOpen())
  {
    // Do the stuff
  }
}

Thanks.
