Using which development environment with which programming language, can you quickly create an application that would communicate with the subd, display tables, change form data, have a directory tree with an unlimited nesting level, buttons, pictures, etc.?
Now we have excel in different data in different files, in large quantities. It has become very long and inconvenient to change something there, add. It is necessary to quickly create an application with a graphical interface and a single base in order to work with subd. I just can not choose a specific environment and language. Can you advise something?
