I am writing a SQL application which I hope to distribute to clients. 90% of the functionality exists in MSSQL, but I want to have a graphical interface for a "setup" screen.

The screen would have several tabs for accessing different functions. The fields on the form would basically map straight into a SQL table (some would be displaying info from SQL, others accepting input).

It needs to be able to pass the windows user's credentials to the SQL database, or allow them to specify a SQL username and password. This application needs to be able to run on any recent windows-based OS.

What is the best language for this? I'm mostly a SQL/R developer, but I have some limited experience with VB and other object-oriented languages. Windows forms was mentioned, but I would appreciate other input. Something on a web-form might look nice but I was hoping to avoid requiring IIS. Thank you!
