So it looks like mago-mi might be helpful for DDT on Windows.
mago-mi supports subset of GDB/MI commands enough for DlangIDE, 
but it can be easy extended.

Currenlty supported commands can be shown using help command (use 
--interpreter=mi2 when running mago-mi, otherwise it will print 
non-MI commands). Also commands are listed in readme file 
https://github.com/buggins/mago/blob/master/MagoMI/mago-mi/README.md

I didn't try DDT with mago-mi, and so I'm not sure which commands 
must be supported by debugger to get it working with DDT.

To get list of commands DDT tries to use you can either add 
--log-file=magomi.log --log-level=TRACE to mago-mi command line 
or use debug build of mago-mi.
It will all STDIN data to log file, and report errors for 
unsupported commands.
