How do I add text inside a shape in XAML

Question

I am working on a Metro App using C++ and XAML. I want to create a polygon shape and add text inside it.

At first I thought of defining my own Controltemplate and apply it to Textblock but unfortunately it does not understand TargetType = "TextBlock".

Secondly, I thought of inheriting the Polygon class and see if I can do anything there but that class is sealed.

Any ideas on how to achieve this?

In WPF XAML you could do something simple like this:

<Grid Width="60" Height="100">
    <Ellipse Fill="Yellow"/>
    <TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" Text="Hello"/>
</Grid>

To get text in the centre of a yellow ellipse.

I'm guessing something that simple will work on WinRT.
