just if 'DISPLAY' not in os.environ is fine

But, for PyGtk 2.8 and earlier I would suggest doing this in a
different manner (and much simpler and less error-prone):

try:
    import gtk
except ImportError, e:
    print e

For PyGtk 2.10 and newer, ImportError is actually a warning so the
code changes a bit:

import warnings
warnings.filterwarnings('error', module='gtk')
try:
    import gtk
except Warning, w:
    print w
warnings.resetwarnings()
