Not if you use an FPGA with either an embedded CPU or a soft-CPU and a
DSP processor. You could write the CPU and DSP code in the language of
your choice. 

Of course this may not be a particularly cheap way to go as FPGA's with
these facilities can be pricey. Also note, you may be working yourself
into a chip with hundreds or thousands of BGA balls to contend with.
Then there are performance issues that must be evaluated.

Depending on the tradeoffs you may or may not want to do it this way,
but it is a possibility.
