Hmmm,

if you have just a kernel you can just use
the command line and set the priority with
start, don't type 

math

just type

start /LOW math.exe

*But* if you dont' use a FrontEnd, where do you have

menues ? If you use the FrontEnd you *must* use MathLink and you
must use a command to launch the kernel ?
