User interface and nose.js

I am new in the app world developing, I have a question that may not have sense…
I am using a node.js solution to connect with a mongodb database from ( in Visual studio. Once I achieved posting and getting data by using node.js solutions I want to do the same by unsing UI from Xamarin VS (login button, with text boxes and so on). The problem is that I have no idea how to use a Xamarin VS solution and combine it with a node.js. I mean, push a button and run node.js code…
That it make sense?
Otherwise, any UI graphic editor recomendation and easy integration with node.js?
