You can use Button click event. In the event you can add some labels on a StackPanel. StackPanel will help when you add something new it will be under the last one.

In XAML:

<Window x:Class="DemoTryThings.MainWindow"
    xmlns:local="clr-namespace:DemoTryThings"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:scm="clr-namespace:System.ComponentModel;assembly=WindowsBase"
    WindowStartupLocation="CenterScreen">

<!--Main Grid!-->
<Grid Margin="10">

    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>

    <StackPanel Grid.Row="0"
                x:Name="LabelStackPanel"/>

    <Button Grid.Row="1"
            Height="30"
            Content="Add Label"
            Click="ButtonBase_OnClick"/>

</Grid>

In cs file:

public partial class MainWindow : Window
{

    public MainWindow()
    {
        InitializeComponent();
    }

    private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
    {
        LabelStackPanel.Children.Add(new Label { Content = "Hi this add with button click!" });
    }
}

And result:
