Unless you have very high-crossplatform skills you will benefit in utilizing existing libraries and platforms, which in turn mean that you will benefit in using the same abstraction layers as the existing libraries and platforms.

In the Windows and Unix world this currently means that you will have a web frontend engine - pretty much self contained with a lot of Javascript oohs and aahs - and a database backend, usually on separate boxes. If it is written in Java, the frontend might even run on the AS/400 itself.

If so, then the trick to invoke programs and get results back is to use stored procedures in SQL calls, which for the jtOpen JDBC-driver works very well, and is fast. I believe that the native .NET-drivers have the same functionality but I have not tested it personally. (For advanced users it has been reported that the jtOpen driver can run in .NET using ikvm).

I believe this to be a sound technical solution. It will take a while before SQL access to the AS/400 platform is deprecated.

If your priorities are different, then the above may or may not apply :)
