Hi,
While we have not had the resources available to create an *official* language interface file, there has been some work on this by fellow users. Please consult http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RNAME=ViewQuestion&HOID=50650000000800000040430000&ECategory=Instrument+Connectivity.VISA for more details.
