Windows API in C/C++

Help, I have no idea how to correctly use the API to create windows and fill them with text and shit.

Give me information, tutorials, etc.

This is your Hello World in 1995 on Win32 and 'C'

#include <windows.h>
LRESULT CALLBACK WndProc(HWND hwnd,
             UINT msg,
             WPARAM wparam,
             LPARAM lparam);
INT WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
         LPSTR cmdline, int cmdshow) {
  MSG         msg;
  HWND        hwnd;
  WNDCLASSEX  wndclass = { 0 };
  wndclass.cbSize          = sizeof(WNDCLASSEX);
  wndclass.style           = CS_HREDRAW | CS_VREDRAW;
  wndclass.lpfnWndProc     = WndProc;
  wndclass.hIcon           = LoadIcon(NULL, IDI_APPLICATION);
  wndclass.hCursor         = LoadCursor(NULL, IDC_ARROW);
  wndclass.hbrBackground   = (HBRUSH)GetStockObject(WHITE_BRUSH);
  wndclass.lpszClassName   = TEXT("Window1");
  wndclass.hInstance       = hInstance;
  wndclass.hIconSm         = LoadIcon(NULL, IDI_APPLICATION);
  RegisterClassEx(&wndclass);
  hwnd = CreateWindow(TEXT("Window1"),
        TEXT("Hello World"),
        WS_OVERLAPPEDWINDOW,
        CW_USEDEFAULT,
        0,
        CW_USEDEFAULT,
        0,
        NULL,
        NULL,
        hInstance,
        NULL);

  if( !hwnd )
    return 0;
  ShowWindow(hwnd, SW_SHOWNORMAL);
  UpdateWindow(hwnd);
  while( GetMessage(&msg, NULL, 0, 0) ) {
    TranslateMessage(&msg);
    DispatchMessage(&msg);
  }
  return msg.wParam;
}
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg,
         WPARAM wparam, LPARAM lparam) {
  switch(msg) {
    case WM_DESTROY:
      PostQuitMessage(WM_QUIT);
      break;
    default:
      return DefWindowProc(hwnd, msg, wparam, lparam);
  }
  return 0;
}

This is your Hello World in 2008 on C# and WPF

using System.Windows;
using System;

class Program {
  [STAThread]
  static void Main() {
    Window f = new Window();
    f.Title  = "Hello World";
    new Application().Run(f);
  }
}

Anyone who wants to do the former needs their heads examined.
