I agree with Oppenhiemer, with odbc connections you have the weakest link to the database. When you install Interbase it provides an odbc driver.
You should try Delphi for the following reasons:
Interbase and Delphi are both from borland thus you will get the most of interbase with Delphi or Borland C++, etc.
Delphi got native controls for Interbase that directly work with the API (application programming interface) of Interbase
With the Datapump Utility you can convert your data from interbase to any other RDBMS (oracle , sql server) and your front-end application only need to point to the new database to run.
There are far more reasons I could find to use Delphi over VB, but I only focussed on the combination delphi x interbase
