Can anyone help me to loft that

Good evening!

Student in product design, I have just started to do 3D models with Rhino and Grasshopper.

I don't know all the tools yet and I would like to know if it's possible to loft two curves that will in a same time do a revolution around a vertical axis (the circle I drew),(see below the attached files).

Thank you very much for your time and help.

(Then, I would like to print it on a 3D model. Anyone have an idea of how much thick this volume should be ? (it s 5cm height).
