My Problem now is that in the function I added to the event table with EVT_SPINCTRL(ID_SPIN_UNEVEN, MyFrame::OnSpinUneven) the Update of the integer doesn't work.

you're only changing the internal event m_position variable in this way.

Rather do:

  void MyFrame::OnGaussSpin(wxSpinEvent &event) {
  	int value = event.GetPosition();
  	m_pMySpinCtrl->SetPosition(val+2);
  }
