How to set multiple buttons, textblocks and textboxes underneath each other in WPF?

Question

Right now I have the following:

<DockPanel Height="150">

    <Button DockPanel.Dock="Right" Padding="5" Margin="5 0 5 0" FontWeight="Bold" Content="Submit" Click="Button_Click"/>
    <TextBlock TextAlignment="Left" Padding="5" Text="DVM Positive Readout" />

    <Border Height="25" BorderBrush="Black" BorderThickness="1" DockPanel.Dock="Top">
        <TextBox HorizontalAlignment="Stretch" VerticalAlignment="Center" x:Name="DVM_Positive_ReadOut" LostKeyboardFocus="DVM_Positive_ReadOut_LostKeyboardFocus" />
    </Border>

    <Border Height="25" BorderBrush="Black" BorderThickness="1" DockPanel.Dock="Top">
        <TextBox HorizontalAlignment="Stretch" VerticalAlignment="Center" x:Name="DVM_Negavtive_ReadOut" LostKeyboardFocus="DVM_Negative_ReadOut_LostKeyboardFocus" />
    </Border>

</DockPanel>

Which results in:

I want to have two submit buttons and two textblocks. The Textboxes are correctly stacked, though it would be nice if they were centered.

You can achieve this by using StackPanel with its horizontal or vertical attribute:

<StackPanel Orientation="Vertical">
        <StackPanel Orientation="Horizontal">
            <TextBlock TextAlignment="Left"
                       Padding="5"
                       Text="DVM Positive Readout" 
                       Width="150"/>
            <Border Height="25"
                    BorderBrush="Black"
                    BorderThickness="1"
                    Width="150"
                    DockPanel.Dock="Top">
                <TextBox HorizontalAlignment="Stretch"
                         VerticalAlignment="Center"
                         x:Name="DVM_Positive_ReadOut"
                         LostKeyboardFocus="DVM_Positive_ReadOut_LostKeyboardFocus" />
            </Border>
            <Button DockPanel.Dock="Right"
                    Padding="5"
                    Margin="5 0 5 0"
                    FontWeight="Bold"
                    Content="Submit"
                    Click="Button_Click" />
        </StackPanel>

        <StackPanel Orientation="Horizontal">
            <TextBlock TextAlignment="Left"
                       Padding="5"
                       Text="DVM Negative Readout"
                       Width="150" />
            <Border Height="25"
                    BorderBrush="Black"
                    BorderThickness="1"
                    Width="150"
                    DockPanel.Dock="Top">
                <TextBox HorizontalAlignment="Stretch"
                         VerticalAlignment="Center"
                         x:Name="DVM_Negavtive_ReadOut"
                         LostKeyboardFocus="DVM_Negative_ReadOut_LostKeyboardFocus" />
            </Border>
            <Button DockPanel.Dock="Right"
                    Padding="5"
                    Margin="5 0 5 0"
                    FontWeight="Bold"
                    Content="Submit"
                    Click="Button_Click" />
        </StackPanel>
    </StackPanel>
