Explorer has a built-in unzipper. Heck, you can still make a
bootable MS-DOS system floppy, if desired (though you can't
use SYS to actually install anywhere).

As for running DOS stuff, it doesn't really work well anymore,
esp. not at all in 64-bit Windows. So unless you want to jump
through hoops (see below), then DJGPP is not for you.

Here's some third-party unzip tools (for Windows) if Explorer
isn't good enough for your needs:

ftp://ftp.sac.sk/pub/sac/pack/unz600xn.exe
http://downloads.sourceforge.net/sevenzip/7za920.zip

Anyways, here's two different ways to run DJGPP:

https://www.virtualbox.org/wiki/Downloads
http://rufus.akeo.ie/

But both of these pretty much expect you to know how to install
DOS yourself (presumably FreeDOS) and grab all the pieces of
DJGPP that you need. (GCC/GPP + BinUtils + DJDEV + Make is
probably the minimum for most people.)

I don't grok C++, so I don't know how well DJGPP supports C++11.
I assume that C++98 is better working overall. And of course there
are lacks of ports of things like Qt or whatnot. You can use Georg's
port of FLTK. At least a packet driver and Watt-32 could let
networking work under VirtualBox. Still, there is no proper Unicode
support.

I guess it just depends on what you're trying to do.
