There is no simple solution for your problem. The display of the close button is tied to the system menu style. There are window styles that allow creation of windows without the system menu icon (WS_EX_DLGMODALFRAME, WS_EX_TOOLWINDOW). But these styles are not for frame windows.

Yes, because they are also system menu commands. The corresponding style flags are provided to disable these buttons with system menus.

You should think about the idea to remove the icon while supporting the system menu commands:
- The icon is the mouse button to open the system menu
- It indicates that there is a system menu that can be also activated with Alt+
- It is helpful when identifying minimized windows (especially when using user defined icons)

It is a general Windows GUI element. Removing such elements or changing the behaviour should be always avoided.

Then you must override the drawing of the non-client area yourself, and perhaps even handle the mous clicking and window dragging as well. That area above the client area where the title bar is drawn is called the non-client area, and some legacy articles here or on CodeGuru might explain how to do that drawing. Yes, it IS complicated. Like Jochen said, you should seriously consider why you want or need to do this.
