  Generally, deriving from native widgets (wxButton, wxTreeCtrl (on MSW),
wxCheckBox, etc, etc, etc) in order to alter their look and feel is
unsupported in wxWindows.

  No, and yes. You can emulate it by using checked and unchecked icons
for tree items (you can use the same trick with Wx::ListCtrl, BTW).
It is correct that you can't currently use wxUniversal widgets
with wxMSW.

  See above.

  AFAIK, no.
