There is also which was a start at 
a C++ client to Accumulo. I'm not sure the state of it. In short, it's 
possible, but like Eric said, the Java client does quite a bit more than 
just RPC to other processes.

Regarding python+proxy, extra RPC is definitely a concern, but I'm not 
sure how much of the performance decrease is the use of an 
interpreted/dynamic language and how much is using the Proxy. I haven't 
ever benchmarked the two to get a good understanding of where the extra 
time is really spent.
