You can have editable treeviews.  However, they don't work like "edit at any
time" spreadsheets.  You'd probably have an Add button to create a new
empty row and place the cursor at the first column (using set_cursor).

If you do decide you want a spreadsheet widget, wxWindows has a very nice
one, if you can get past the creaky API.

I believe that in 2.3 you can have the new combo box widget in a treeview,
but I'm not sure about that.  And, supposedly it's "easy" to implement your
own custom renderer in 2.2, though I think that requires more intamacy with
the internals of Gtk than I care to learn about.  

What I do instead is pop up a window on a keypress with a list in it (I gave
up trying to place the popup exactly; it just is not practical; I just pop
it up in the center).

But Gtk apps *should* work under Windows if they don't have unix specific
things in them.
