I like

    if dlg.ShowModal() == wx.ID_OK:
         db_name = dlg.GetValue()
    else:
         db_name = None
    dlg.Destroy()
    return db_name

better than

    db_name = None
    if dlg.ShowModal() == wx.ID_OK:
         db_name = dlg.GetValue()
    dlg.Destroy()
    return db_name

but I suppose it's a matter of preference.
