I see there is a lot going on now.
I have already written DFTB in Gromacs, so it is fully integrated in there (rather than a separate package) and I use the PME routines of Gromacs.
I would be happy to contribute. What I do not know is if it is necessary to re-write my code in C++, or if it is fair enough to modify the interface (input/output data structures) somehow.

Yes it is. Any new code can only go into the master branch, and in the
master branch a transfer to C++ is obligatory. We (read: Lee-Ping) are
now working hard to build a framework in C++ for this - from scratch. A
basic layout will be available in some days. The main idea is to split
off quantum package specific code into separate classes. You are of
course welcome to contribute!
The development is being done in a separate branch for now, called qmmm.
What is not clear to me is whether the DFTB code you are working on is
included in gromacs or by using a separate package? Which one in that case?
