As far as I know, not currently. However, there is some discussion in the user forum from an individual who has implemented an OIL client in C#. You could do the same in C/C++. However, an easier way would be to use CodeMesh Courier (www.codemesh.com/en/evaluation_jmscourier.html).
Or, if you're on Windows and want to do COM you could take a look at Active JMS (active-jms.sf.net) which I wrote to bring JMS to the COM world.
By the way, in the future, please direct questions like this to the user forums above.
