Just put

  bin_PROGRAMS = mine
  mine_SOURCES = main.c gtk/gtk.c gtk/gtk.h

in src/Makefile.am.

If you're dying to have another Makefile in src/gtk, you can create a
library as an intermediate step (add AC_PROG_RANLIB in configure.ac
then):

src/Makefile.am:
bin_PROGRAMS = mine
mine_SOURCES = main.c
mine_LDADD = gtk/libgtkstuff.a

src/gtk/makefile.am has
noinst_LIBRARIES = libgtkstuff.a
libgtkstuff_a_SOURCES = gtk.c gtk.h

But I really recommend the first variant.

Cheers,
