Best example code found so far:

• Using Windows 7 taskbar features in PyQt
• wxPython and windows 7 taskbar (implementation for the link above)
• taskbar support for scummvm (win32 and unity) (only used for showing progress bar and recent items?)

The examples in comment:4 work but this is not the interface we need. We could still use them to enhance the tray/menu classes with progress bar support, etc.

• make the tlb:

  midl TaskbarLib.idl /tlb TaskbarLib.tlb
  

• use it with GTK: (requires comtypes)

  import gtk
  window = gtk.Window()
  window.show()
  import comtypes.client as cc
  cc.GetModule("TaskbarLib.tlb")
  import comtypes.gen.TaskbarLib as tbl
  taskbar = cc.CreateObject("{56FDF344-FD6D-11d0-958A-006097C9A090}", interface=tbl.ITaskbarList3)
  taskbar.HrInit()
  taskbar.SetProgressValue(window.get_window().handle,40,100)

For the menus, what we want is AddUserTasks. There is some support for it in pywin32 already:

> from win32com.shell import shell
> shell.CLSID_DestinationList
IID('{77F10CF0-3DB5-4966-B520-B7C54FD35ED6}')

By the looks of things, "tasks" is not it: present even when the application is not running. Maybe Jump Lists? But even that is not a good fit...

The only workable solutions that I can think of are:

• Setting up a custom title bar – reprise)
• reserve some space at the top of the window for a regular gtk menu

Both of which would have all sorts of interesting interactions with window hints, size constraints, events, position...

Unrelated:

• along the way, found this useful com example: Accessing unregistered COM objects from python via a registered TLB.
• I can create "shell items" with:

  import pythoncom
  pythoncom.CoCreateInstance(shell.CLSID_ShellItem, None, pythoncom.CLSCTX_INPROC_SERVER, shell.IID_IShellItem)
