foreach ( var s in textArray )
{
  Button b = new Button();
  //set button width/height/text
  ...
  myCanvas.AddChild( b );

  // position button on canvas (set attached properties)
  Canvas.SetLeft( b, ... ); // fill in the ellipses
  Canvas.SetTop( b, ... );
}

<!-- ItemsControl is a customisable way of creating a UI element for each item in a
collection.  The ItemsSource property here means that the list of items will be     selected
from the DataContext of the control: you need to set the DataContext of this control, or
the window it is on, or the UserControl it is in, to your array -->

<ItemsControl ItemsSource="{Binding}">

    <!-- The Template property specifies how the whole control's container should look -->
    <ItemsControl.Template>
        <ControlTemplate TargetType="{x:Type ItemsControl}">
            <ItemsPresenter/>
        </ControlTemplate>
    </ItemsControl.Template>

    <!-- The ItemsPanel tells the ItemsControl what kind of panel to put all the items in; could be a StackPanel, as here; could also be a Canvas, Grid, WrapPanel, ... -->
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Vertical"/>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>

    <!-- The ItemTemplate property tells the ItemsControl what to output for each item in the collection.  In this case, a Button -->
    <ItemsControl.ItemTemplate>
        <DataTemplate>

            <!-- See here the Button is bound with a default Binding (no path): that means the Content be made equal to the item in the collection - the string - itself -->
            <Button Content="{Binding}" Width="200" Height="50"/>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>
