Yes, it's easy enough. For example  the following file can be run by a
C compiler or interpreter, a  Fortran compiler or interpreter, or a sh
or csh interterpreter.

----------(happy.source)-----------------
cat /*dev/null; echo "Happy New Year"\!
cat <<c*/ /*dev/null | cat > /dev/null
c */ () {} /*
c */ main() { cat(); printf("Happy New Year!\n"); } /*
17      format('Happy New Year!')
        write (6,17)
        stop
        end
c*/
-----------(Makefile)-------------------
all: happy-c happy-f happy-sh happy-csh
        @ echo -n '(C)      '
        @ ./happy-c || true
        @ echo -n '(FORTRAN)      '
        @ ./happy-f
        @ echo -n '(Bourne Shell) '
        @ sh ./happy-sh
        @ echo -n '(C Shell)      '
        @ csh ./happy-csh
    
happy-c:happy.source Makefile
        @ cp happy.source happy-c.c
        @ gcc -o happy-c happy-c.c

happy-f:happy.source Makefile
        @ cp happy.source happy-f.f
        @ f77 -o happy-f  happy-f.f 2> /dev/null

happy-sh:happy.source Makefile
        @ cp happy.source happy-sh
        @ chmod 755 happy-sh

happy-csh:happy.source Makefile
        @ cp happy.source happy-csh
        @ chmod 755 happy-csh

clean:
        -rm -f *.o *~ happy-csh happy-sh happy-f happy-f.f happy-c happy-c.c
