If you created two ResourceDictionary files you can binding by DynamicResource.

Example:

First resource file (Lang.en-US.xaml):

    Username:
    Password:
    Close
    Login        

Second resource file (Lang.pl-PL.xaml):

    Login:
    Hasło:
    Zamknij
    Zaloguj

Set default language in Application resources:

Let's say that we have ComboBox like below:

Code-behind SelectionChanged:

 private void cbLang_SelectionChanged(object sender, System.Windows.Controls.SelectionChangedEventArgs e)
        {
            ResourceDictionary dict = new ResourceDictionary();

            switch (((sender as ComboBox).SelectedItem as ComboBoxItem).Tag.ToString())
            {
                case "en-US":
                    dict.Source = new Uri("Lang.en-US.xaml", UriKind.Relative);
                    break;
                case "pl-PL":
                    dict.Source = new Uri("Lang.pl-PL.xaml", UriKind.Relative);
                    break;
                default:
                    break;
            }
            this.Resources.MergedDictionaries.Add(dict);
        }

And you can binding like this:
