Das Thema ist irgendwie geschlossen worden (keine Ahnung warum), daher neuer Thread:

Show() und Update() fehlen; außer dem fehlt das "return 0;" aus WinMain().

Hier der lauffähige Code (alles in einer Pelle):

#include <windows.h>

class Window
{
  private:
   HWND hWindow;
  public:
   void Create(LPCTSTR lpClassName, LPCTSTR lpWindowName, DWORD dwStyle, int x, int y, int nWidth, int nHeight, HWND hWndParent, HMENU hMenu, HINSTANCE hInstance, LPVOID lpParam);
   void SetLong(int nIndex, LONG dwNewLong);
   void SetPos(HWND hWndInsertAfter, int X, int Y, int cx, int cy, UINT uFlags);
   void Destroy();
   void Show(int nCmdShow);
   void Update();
};

void Window::Create(LPCTSTR lpClassName, LPCTSTR lpWindowName, DWORD dwStyle, int x, int y, int nWidth, int nHeight, HWND hWndParent, HMENU hMenu, HINSTANCE hInstance, LPVOID lpParam)
{
    hWindow = ::CreateWindow(lpClassName, lpWindowName, dwStyle, x, y, nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam);
    if(!hWindow) throw(GetLastError());
}
void Window::SetLong(int nIndex, LONG dwNewLong)
{
    if(!::SetWindowLong(hWindow, nIndex, dwNewLong)) throw(GetLastError());
}
void Window::Destroy()
{
    ::DestroyWindow(hWindow);
}
void Window::SetPos(HWND hWndInsertAfter, int X, int Y, int cx, int cy, UINT uFlags)
{
    if(!::SetWindowPos(hWindow, hWndInsertAfter, X, Y, cx, cy, uFlags)) throw(GetLastError);
}
void Window::Show(int nCmdShow)
{
   ::ShowWindow(hWindow, nCmdShow);
}
void Window::Update()
{
   ::UpdateWindow(hWindow);
}

LRESULT CALLBACK WindowProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
   switch (message)
   {
   case WM_DESTROY:
      {
         PostQuitMessage(0);
         return 0;
      }
   }
   return DefWindowProc(hWnd, message, wParam, lParam);
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
    MSG msg;
    WNDCLASS wndclass;
    wndclass.style = CS_HREDRAW | CS_VREDRAW ;
    wndclass.lpfnWndProc = WindowProc;
    wndclass.cbClsExtra = 0 ;
    wndclass.cbWndExtra = 0 ;
    wndclass.hInstance = hInstance ;
    wndclass.hIcon = ::LoadIcon (NULL, IDI_APPLICATION) ;
    wndclass.hCursor = ::LoadCursor (NULL, IDC_ARROW) ;
    wndclass.hbrBackground = (HBRUSH) ::GetStockObject (WHITE_BRUSH) ;
    wndclass.lpszMenuName = NULL ;
    wndclass.lpszClassName = "Die erste WNDCLASS";
    RegisterClass(&wndclass);

    Window win;
    win.Create("Die erste WNDCLASS", "Die erste WNDCLASS", WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, NULL, NULL, hInstance,  NULL);
    win.Show(SW_SHOWNORMAL);
    win.Update();

   while (GetMessage(&msg, NULL, 0, 0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }
   return 0;
}

Der Thread wurde nach WinAPI verschoben, weil er da auch hingehört
