Similar to how you would do it on the web, you can just put the tab control and floating control inside a Grid and set the margins of the floating control to get it in the right spot. You could also use a Canvas element to contain the Grid and floating control and set the Canvas.Left and Canvas.Top.
You might need to dynamically measure the width of each tab, if the tabs are not determined at compile time.
