Any windows95 and later compatible compiler will, in theory, allow you
to make a DLL file that can be used by IDL's CALL_EXTERNAL procedure.
You need to look in the 'External Development Guide' of the IDL help (or
the 'Advanced Development Guide' of the IDL 5.0 help) for what
constitutes an IDL-useable DLL.
As for the C programming, creating a DLL is not that complicated, and
there should be documentation for doing this with whatever compiler you
use- for example, see
for information about the GCC compiler.
Finally, a general-purpose Win32 programming text will have usefull
information about how to write DLLs. Charles Petzold's book
'Programming Windows 95' is the definitive source for most basic windows
