hints.flags = MWM_HINTS_DECORATIONS;
hints.decorations = MWM_DECOR_BORDER | MWM_DECOR_RESIZEH;

Whether or not your WM respects this is up to the WM.

Add WM_DELETE_WINDOW to WM_PROTOCOLS. This will typically case the WM
to send a ClientMessage event with WM_DELETE_WINDOW as the type atom,
rather than simply destroying the window. The application can simply
ignore the message.

However, like a lot of things in X, this relies upon the WM
cooperating. If the WM also provides a feature to "destroy" (as
opposed to "delete") a window, you can't prevent this.
