I am creating a windows program using gdi.  Besides the main window I need to be able to create a second, smaller window every once in a while.  To display info and stuff...    

I want to interact with the second window in a similar way to the first one.  But I dont want them to get all tangled together and stuff....   Any simple solutions to creating this popup window and working with it?

Just use the normal CreateWindow and switch between them with SetFocus(hwnd).  Don't forget that the message pump gives your WNDPROC the HWND associated with the message.

If you don't want to deal with that, perhaps you can settle for a child dialog window.

Thats the HWND parameter to your WNDPROC.

Presumably, you have something like:

HWND Window1;
HWND Window2;
then in your WNDPROC, something like

       case WM_PAINT:
            if (hWnd==Window1)...
            else ...
            return 0;
