You can pretty much lift all the original code. Microsoft tried to make the WPF names match the WinForms names so this could be done.
There is no appendtext method on text boxes. I would simply do $TextBox.Text = $TextBox.Text + "New text" Bindings aren't really needed for text boxes and things like that. They are required for DataGrids (though it could happen in the background without you knowing) but I did a lot of work in WPF without doing any bindings. Simply interact directly with the controls (like I did above for the text box). Bindings greatly help the process along when you thread, but it's not a big deal if you don't.
