No, I think it cannot be considered WCAG 2.0 compliant.

Even if you "meet" the SC 1.1.1 in terms of "providing alternatives", 
the technique would not meet Conformance Requirement #4, because it is 
not an "accessibility supported way of using the technology" (in this 
case, CSS).

The technique is not accessible when users turn high contrast mode on, 
so I consider it would fail if it is "tested for interoperability with 
users' assistive technology", which is the first condition of the 
"accessibility supported" definition.

Take into account that users of high contrast mode (me included) will 
not see anything in the place of the button. Even if the buttons get 
focus, there is no chance to know their purpose. Indeed, it is likely 
that the user will ignore their existence.
