C++ or C# Tree View Example

I need some help from someone with good GUI and architecture ability to help lay out a project. I want someone to make the main layout for my program. What I need you to do is the following: 1. Make a project. 2. A tree on the left. 3. 3 nodes on the tree A, B, C 4. A working area on the right with changing pages that will be used for a variety of calculators. Notice each page has a different update trigger. 5. When Node A is active, the working area shows a page with only a. Two text boxes to enter a number for inputs b. One textbox for an answer c. One button that when pressed adds the two entry text boxes and puts the answer in the answer text box. 6. When Node B is active, the working area shows a page with only a. Two text boxes to enter a number for inputs b. One textbox for an answer c. When the keyboard Enter key is pressed the two entry text boxes are multiplied and the answer is put in the answer text box. 7. When Node C is active, the working area shows a page with a. Two text boxes to enter a number for inputs b. One textbox for an answer c. When the two entry text boxes filled, the entries are multiplied and the answer is put in the answer text box. When you are done, I will continue to add several hundred more nodes to the tree and corresponding pages, My request to you is to please make an example of an efficient and orderly way to make all of the pages considering that I will make hundreds of them and want to have an easy way to show and hide the pages for editing. Ideally I would like to use Visual Studio C++, (unless that is a bad choice) I installed Visual studio C++ and did not find the Toolbox that I am used to when working with VB.net. If for some reason Visual studio C++ is a bad choice for this project I am open to suggestions to use something else. It would be best for me to use C++ Express because that is what some other projects are developed in that I want to join in on and I need to gain some experience in that on my own project first. Thanks for looking.
