Do
import gtk
and then you can use any Gtk+ widgets and functions.

For instance like this, for the current channel:
container = gwy.gwy_app_data_browser_get_current(gwy.APP_CONTAINER)
field = gwy.gwy_app_data_browser_get_current(gwy.APP_DATA_FIELD)
mask = field.new_alike(False)
mask.fill(1.0)
i = gwy.gwy_app_data_browser_get_current(gwy.APP_DATA_FIELD_ID)
container.set_object_by_name("/%d/mask" % i, mask)

The minimum and maximum value are stored under "/0/base/min" and
"/0/base/max" (the locations are a bit silly, but they are like this for
historical reasons).
I admit the location of various things are not properly documented
anywhere. If you encounter this, gwydump can often help you by showing
you the content of .gwy files with the corresponding things present.

I'm not sure why.

They are reference-counted. So they should disappear when they get out
of scope (of course, if you did not put them into the data container or
so), also explicit del should work.
