Did you  mean something like this?

        wxWindowList::Node* node = wxTopLevelWindows.GetFirst();
        while (node)
        {
            wxWindow* window = (wxWindow*)node->GetData();
            if (window)
            {
                 ...
            }
            node = node->GetNext();
        }

There is not much information about wxTopLevelWindows, but it seems (and 
my experiments confirm) that, wxTopLevelWindows has no information about 
native dialogs.
   
The code above returns information only about frames inherited from 
wxFrame that I create directly  (Option\About windows). But does not see 
system dialogs i.e.

    wxFileDialog dlg(this);
 or 
   m_findDialog = new wxFindReplaceDialog( this, &m_findData, _("Find"), 
wxFR_NOWHOLEWORD );

The same problem, it works only for wxWidgets window, does not work for 
native dialogs:(
