Here is the answer of ChatGPT4 when asked the same question about the status bar (I truncated the code output because it's very long):

Using the Shell Common Controls in Windows 3.1 can be a bit tricky due to its older architecture and limited capabilities, but it's certainly doable.

However, there are a few complications to note:

1. Windows 3.1 does not natively support the status bar as a control. Status bars are part of the Common Controls library introduced in Win32, specifically, it was introduced in Windows 95 with COMCTL32.DLL. Windows 3.1 is a 16-bit environment and does not include this library.

2. If you want a status bar in a Windows 3.1 application, you'll have to draw and manage it yourself.

3. Windows 3.1 programming is largely obsolete. It can be a fun academic exercise or a necessity for maintaining legacy software, but if you're developing new software it would be much more practical to use a more modern version of Windows and its associated API.

Assuming that you still want to go ahead, here's a basic idea of how you might implement a status bar yourself:

  ```c
  #include <windows.h>
  
  #define ID_STATUS 100
  
  LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
  
  int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, 
      PSTR szCmdLine, int iCmdShow) 
 {
