For an instrumentation application, C++ is a very sane choice. There are

You seem to presume that one must code the whole thing in one language as a
monolithic application. I don't expect some of my deployments to have a
display. It might be a little "brick" computer buried in a rack or inside
some OEM factory equipment.
I expect to code the "back end" that talks to the hardware in C++, because
my vendors' expose their API's either as C++ or C, and because I will be
exposing an API to my customers. But the front end is going to be separate
and may be attached either as a linked application (ie. exe/dll or
executable/so) or via TCP/IP, possibly local. There may even be multiple
"heads", with some acting as remote monitors while others act as control
panels.
One reason I don't want a monolithic application is because it gives me the
freedom to try different front-ends based on platform support for control
libraries. I might have a web front-end using SVG, a local one with Qt, or
perhaps something using Java for either.
I expect any control library will give me the common stuff like windows and
radio buttons. It's the more esoteric stuff like oscopes, gauges, and knobs
that I'm trying to nail down.
