A search pulled up the code below, but that seems like a lot of work just to 
get the HWND.

Isn't there something basic?

Code:
// -----------------------------------------
HWND  g_hwnd;
int  g_nFound;

BOOL CALLBACK FindHwndFromPID( HWND hwnd, LPARAM lParam) :

HWND GetHwndFromPID ( DWORD dwProcessId)
{
 g_hwnd = NULL;
 g_nFound = 0;
 EnumWindows (  FindHwndFromPID,    ( LPARAM) dwProcessId));
 if ( g_hwnd)  // we found one...
      return ( g_hwnd);
 // nothing found :-(
 return (NULL);
}

BOOL CALLBACK FindHwndFromPID( HWND hwnd, LPARAM lParam)
{
    DWORD   dwPID2Find  =   ( DWORD) lParam;
    DWORD   dwPID       =   0;
    if  (   GetWindowThreadProcessId    (   hwnd,   &dwPID))
        {
            if  (   dwPID   ==  dwPID2Find)
                {
                    g_hwnd  =   hwnd;
                    return  (   FALSE);
                }
        }
    return  (   TRUE);
}

And call 'GetHwndFromPID()' like

Usage:
// -----------------------------------------
HWND hwnd = GetHwndFromPID(GetCurrentProcessId());

which will retrieve the top-level window handle for your app.
