I-Net compatible Windows-based query tool

I need to identify a query tool like SQL Editor that runs under Windows NT 4.0 and uses I-Net as the transport protocol. I want a simple interface to enter SQL commands and submit them to Informix 7.2.2 running on a server. I don't want ODBC or a simple socket connection. I specifically need I-Net compatibility. This is because I want to "capture" (record) the SQL messages using Mercury Interactive's LoadRunner. LoadRunner understands I-Net transport protocol.
