That may be the case, but Jeff brought up some good points.  It looks odd
to create a window in this fashion (it looks procedural rather than OO).  A
more typical approach would be something like:

class testtt(wxDialog):
    def __init__(self, parent, id):
        wxDialog.__init__(self, parent, id, "")
        basicSizer = wxBoxSizer(wxVERTICAL)

        gridSizer= wxFlexGridSizer(cols=2)

        t=wxStaticText(self, -1, "Eingabe:")
        tt=wxTextCtrl(self, -1, "", size=wxSize(100,-1))
        gridSizer.AddMany([
            (t, 0, wxALL | wxALIGN_RIGHT),
            (tt, 0, wxALL |wxALIGN_LEFT)
        ])

        gridSizer.SetSizeHints(self)
        gridSizer.Fit(self)
        self.SetSizer(gridSizer)
        self.SetAutoLayout(true)
        self.Layout()


And then elsewhere:

dlg = testtt(None, -1)
dlg.ShowModal()

Also, I notice that your calls to gridSizer.Add are incorrect.  The second
argument is supposed to be a boolean flag indicating whether the widget
should be expanded in the sizer's primary direction (in the case of a
wxFlexGridSizer, I'm not sure what that means, but you still need the
argument, at least as a placeholder).  The wxALL and wxALIGN_* flags should
be the third argument.
