If I have an MFC dialog with a button control on it, is there a way to get construct the HWND or CWND for that control using the button's ID (e.g IDC_BUTTON_YES)?

If you use GetDlgItem to get the CWnd pointer, do not store it for later use. There's no guarantee it will be valid later on as it may be a temporary pointer. – rrirower Jan 18 '15 at 23:54

Yes, you can use the function GetDlgItem of the MFC dialog!
Here is an example for you:
CWnd* myWnd = this->GetDlgItem(IDC_LIST1);
// as CListBox
CListBox* myListBox = (CListBox*)this->GetDlgItem(IDC_LIST1);
