How to add NumberField (Touchkit) Component into a GWT ComplexPanel?

Well we are always into migrating Vaadin 6.* to Vaadin 7.* . Into Vaadin 6.* we use lot of GWT Components. Now i want to use the Vaadin Touchkit Component : NumberField to remplace a TextBox component. But it seems likely not to be possible. Is there a way to use vaadin ui component into a GWT Component?

I found it!! There is for (each ?) Touchkit Component a GWT Correspondant!!
