I am using Excel quite well, but I want to make something more on Excel.

I want to prepare a custom menu, which includes some special statistical functions for special purposes.

Which is the appropriate environment to develop an installable add-in in Excel

The best place to discuss this would be the excel.programming newsgroup. The specialists there can discuss in great detail what kind of approach is best for your particular needs. When you ask, specify the versions of Excel you plan to support.
