What's a simple way to make this shape?

How do I simply make this shape?

I’m quite confused on how to make it…

Also, how to make that whole form? With the detail and all

I guess it would be easy to use “proportional editing object” as in the screenshot and use “smooth” or “sphere” :

Start simple: rectangles and circles (boxes and cylinders):

create a 2D cross section, draw a curve in the shape of that part.
Now extrude the cross section on the curve:

As @Okidoki said, try to bring everything back to basic primitives and curves. Think of how something would be build in real life.

Good luck!

As for the details, do you mean the profile around the edge?
