Grasshopper can indeed drive NURBS surfaces in Rhino if I remember correctly, yes. But it suffers from the same problem I describe initially- you have to start with design from Grasshopper- it is a one-way-flow. There is no way to parametrically model something in Rhino and have it automatically generate a model graph that can then be reused.
This is the main difference between tools like Rhino and the aforementioned parametric modelers (Autodesk Fusion360 is another fully parametric solid modeler that supports a 'tree' build with parameters that can then be changed at will at any time, and the model will rebuild).
What is the end result you want? If you're modeling by hand, why do you want to "program" the model later? What would that look like? What units would you operate on? What would the output be? etc.
