Artificially sending a wx event does not get translated into the native 
equivalents and sent on to the native widget.  The wx events are meant 
for going the other way: notifying your code when the native widget 
sends us a native event/message/callback/whatever.

In order to do what you want you would have to use the native API to 
send the native version of the low level mouse events (enter window, 
left button down, left button up, leave window) that the button would 
use to generate a button command event.  wx has no built-in support for 
that.
