 Assuming the WM gives a damn about those. Hints are just that, hints and the 
WM is not required to obey them (or even implement them). For minimize, I 
don't think there's any good way to prevent that and, quite frankly, I don't 
see why anyway. That actually applies to most of it, what exactly is the 
point of disabling just e.g. minimize or maximize? Switch virtual desktops 
and it's "minimized" anyway, resize the window manually and it's "maximized" 
just as well.

 For maximize, most WMs will decide to obey the maximum size and not offer 
maximize for windows that are smaller then the workarea. For closing, your 
app may ignore the WM_DELETE_WINDOW request, although that will not affect 
the close button appearing. Also note that some WMs let you configure which 
buttons are shown in the decorations.
