It would add considerably to the complexity of the X11 VM - Xlib does  
not provide a dialog box call, whereas Win and Mac libraries do.

You could try to write it using Xlib calls, which would involve  
laying out text, drawing a button, having another event loop etc. No  
fun, besides you would get complains that it does not follow the  
user's desktop theme or native language. Or you could make the VM  
depend on GTK or KDE which we have avoided so far.
