wxPython/Tkinter/pyGTK

[Padraig Brady]

Hi,
I'm just starting to use python, and my first
app will have the following widgets:

Tabbed interface, with tabs in horizontal position.
toolbar.
treeview.
listview (with embedded checkboxes)
the odd button.

like:

+--------------------------+
| MyApp                    |
+--------------------------+
|       toolbar            |
|--------------------------|
| tab1 +-----------------+ |
| tab2 |  treeview &/or  | |
| ..   |  listview       | |
| tabn +-----------------+ |
+--------------------------+

So

1. I'm wondering what to use?
    wxPython, Tkinter, PMW+Tkinter or pyGTK

2. Is there any documents comparing
    these options.

3. Are there other options I haven't considered.

4. What option do people consider as having
    the least dependencies (easiest to install),
    as this app is GPL'd and must be easy to install.

Thanks,
Padraig.
