You are unlikely to be able to make the modules in less than 100 off
quantities for less than the off the shelf systems.

If you intend to use the same PCB at both ends, you will be wasting money,
and board real-estate.

Any chip can be programmed in a high level language if you buy the
suitable compiler. The part of this that will be incredibly difficult, is
talking to the 'cheap USB-Bluetooth module'. USB, is a master-slave
interface. The PC implements the master, and the master device is
relatively complex, and needs a _lot_ of code. Slaves are cheap to
implement. The USB-bluetooth interface, is a slave device. There are
dozens of processors that offer USB-slave interfaces, but a USB master
interface (which is what you would need to talk to such a device), will
involve adding a master interface chip, and programming this. You can
reckon on perhaps 60 man days of programming to implement such an
interface.
Much cheaper to use a Bluetooth module that is designed to interface to a
microprocessor. These will cost more, but will bring the amount of code
down to a few man-hours of work. A typical module would be:

TDK do cheaper version, that require a little more work.
There are also such units, with a processor built in, like:
