Simply Application-to-Application Sample

Hello,

I want to create an SAP Object from our external application. I want to fill out some data in this object and then display the SAP GUI containing the created object. The code in our application can be written in C# or C++.

What is the simpliest way to do this?

Which technology should i use?

Where can i find an example?

Which documentation should i use?

Thanks for every response
