With a hardware firewall is it possible to grant some applications
access to say, port 80 and have it blocked for others?

The answer is “it depends”. If you want that level of security, typically
you require “stateful inspection” of packets. This kind of firewall often
costs more. They will inspect the contents of packets and if they
recognize the application sending the packet and if it adheres to certain
rules about the packet content, it will allow the packet to go. This
requires the vendor to know about the applications you intend to use and
program this info into the firewall.
Not quite the same as “if netutil.exe wants to use port 9999 then let him
do so, otherwise no”.
