LRESULT CALLBACK WindowProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam);

int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE, PWSTR nCmdLine, int nCmdShow)
{
const wchar_t CLASS_NAME[] = L"NULL";
WNDCLASS wc = {};
wc.lpfnWndProc = WindowProc;
wc.lpszClassName = CLASS_NAME;
wc.hInstance = hInstance;
RegisterClass(&wc);

HWND hWnd = CreateWindowEx(0, CLASS_NAME, L"Assault Cube", WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, NULL, NULL, hInstance, NULL);

if (hWnd == 0)
return NULL;
ShowWindow(hWnd, nCmdShow);
nCmdShow = 1;
MSG msg = {};
while (GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return 0;
}

LRESULT CALLBACK WindowProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
switch (uMsg)
{
case WM_DESTROY:PostQuitMessage(0);
return 0;
case WM_PAINT:
{
PAINTSTRUCT ps;
HDC hdc = BeginPaint(hWnd, &ps);
FillRect(hdc, &ps.rcPaint, (HBRUSH)(COLOR_WINDOW + 2));
EndPaint(hWnd, &ps);
}
return 0;
case WM_CLOSE:
{
if (MessageBox(hWnd, L"Do you want to exit?", L"EXIT", MB_OKCANCEL) == IDOK)
DestroyWindow(hWnd);
return 0;
}
}
return DefWindowProc(hWnd, uMsg, wParam, lParam);
}

A button is a kind of window created by CreateWindowEx or CreateWindow
Have a look here:

First, that isn't a Window Forms program. Its an SDK style Win32 app.

Second, it isn't a script. Its C++ source code which a compiler will translate into binary.

Third, it isn't in code tags, making the reading of it difficult.

And there are other issues.

But here is a version modified slightly to run on my GCC compiler that shows how to create buttons...
