I am editing a recently asked question and making it specific, taking the advice of some people here.

I would like to program of the following simple form:

1. The user can produce X number of resizable frames (analogous to HTML frames).
2. Each frame serves as a simple text editor, which you can type into and save the whole configuration including resized windows and text.
3. The user should be able alternately "freeze" and present the information, and "unfreeze" and edit frames.

I want to use C## with WPF, in Microsoft's Visual C#.

I do not yet know this language. I am sure I can pick up the syntax, but I would like to ask about some general advice for how to structure such a program. I have never made a GUI program, let alone one that interfaces with a notepad or some basic text editor. Can someone either direct me to a good resource that will teach me how to do the above? Or outline the basic ingredients that such a program will require, keeping in mind that though I know some C and Python, I have no experience with GUIs or advanced programming generally?

In particular I don't know how to incorporate this "text editor" aspect of the program, as well as the resizable frames

I would greatly appreciate any help.
