Some resources that may help you:

Examples in many languages of communicating with NetworkManager via
D-Bus or NM's helper libraries:
http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples

A description of the NM D-Bus API, which many of the examples use:
http://projects.gnome.org/NetworkManager/developers/api/09/spec.html

A description of the configuration that you'll use to create your adhoc
connection:
http://projects.gnome.org/NetworkManager/developers/api/09/ref-settings.html

Essentially, you're creating a wifi connection just like :
http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples/python/add-system-wifi-connection.py

except that's for 802.1x.  You'll want to skip the 802.1x setting, and
instead do something like:

s_wifi = dbus.Dictionary({
    'ssid': dbus.ByteArray("my adhoc"),
    'mode': 'adhoc'})

for an open network.  If you want security, you're currently limited to
WEP, because the kernel has bugs that cause WPA Ad-Hoc networks to fail,
and WPA2 Ad-Hoc support in the kernel is limited, and you also need a
supplicant built with CONFIG_RSN_IBSS.
