Can I create in Visual C++ Window without border and without title bar (Not
in MFC)?

Yes, create a popup window with no border. If you don't want it to have a
"button" in the taskbar make it a toolwindow. Something like this (which has
not been compiled):

    CreateWindowEx(WS_EX_TOOLWINDOW,
                                 "yourWindowClass", "yourCaption",
                                    WS_POPUP | WS_VISIBLE,
                                      pt.x, pt.y, width, height,
                                        NULL, 0, GetModuleHandle(NULL),
NULL);
