You can get around the need for touching GVariant by passing what you
get from get_secrets() to NMConnection's replace_settings() call too. 
Then you get a nice NMConnection object, with only the secrets filled
in.  For example, pass a connection UUID as the argument to this:

#!/usr/bin/env python
import gi
gi.require_version('NM', '1.0')
from
gi.repository import GLib, NM
import sys

client = NM.Client.new(None)
c = client.get_connection_by_uuid(sys.argv[1])
wifi_secrets = c.get_secrets(NM.SETTING_WIRELESS_SECURITY_SETTING_NAME)
wifi_secrets_con = NM.SimpleConnection.new()
wifi_secrets_con.replace_settings(wifi_secrets)
wsec = wifi_secrets_con.get_setting_wireless_security()
print "%s" % wsec.get_psk()
