Use winword.exe command to launch OO Writer

Our organization uses IBM AS/400 systems for most of our accounting and database needs. I have Ubuntu 7.10 connecting to our network, and, using IBM's iSeries Client software for Linux, to our AS/400 systems. The problem I have run into is that for some reports the AS/400 system generates a MS Word document and passes it through to the PC by calling winword.exe. On a Windows PC, I have made it work with Open Office Writer by adding the Open Office folder to the path and renaming the swriter.exe to winword.exe. With these simple changes, when I call up a document on the AS/400, it opens Writer and passes through the document.

Is there a way to accomplish something like this on Ubuntu? This seems to be the last hurdle before we can start using Ubuntu instead of Windows on our desktop systems.
