Yes, this is possible with a GtkComboBoxEntry.  Here is an example I
use, using Glade and GtkBuilder:

Glade code:
<object class="GtkComboBoxEntry" id="host_entry_cmbox">
  <property name="visible">True</property>
  <child internal-child="entry">
    <object class="GtkEntry" id="host_entry">
      <property name="visible">True</property>
      <property name="can_focus">True</property>
      <signal name="activate" handler="on_host_entry_activate"/>
      <signal name="changed" handler="on_host_entry_changed"/>
    </object>
  </child>
</object>

Python code:
def populate_cmbox_hostlist_entry_completion(self):
    hostnames = read_hostsfile()
    if hostnames:
        completion = gtk.EntryCompletion()
        hosts = gtk.ListStore(str)
        for hostname in hostnames:
            iter = hosts.append()
            hosts.set(iter, 0, hostname)
        self.host_entry.set_completion(completion)
        completion.set_model(hosts)
        completion.set_text_column(0)


Hope that helps,
