Yes; dwell method's target users can point but cannot readily click.
For instance, some head tracker and eye-gaze users fall into this
category. It can also be useful for certain other mobility problems in
which click, while possible, is inadvisable (this last category of users
is similar to the primary target use of KMousetool).

I'm not sure what you mean by "dwell" mode here. In AT terminology that
usually means making mouse clicks by hovering over an area. As far as I
know GOK does not have this feature built i, but you can use KmouseTool.
We should really get this built into X IMO. You may be thinking of
switch operation, of which GOK has a much more advanced implementation
I suppose it might be possible to code an on-screen keyboard directly
into GDM, but this might be more work than you think. Note GOK supports
"dwell" mode so that it works for users who can only manipulate a single
button. Making an on-screen keyboard that supports the same sorts of
disabilities that GOK supports might be tricky.
As David infers, GOK does have pointer control which can be used in
dwell mode, allowing a "pointer only" user to move and click the core
mouse pointer (and do drag-and-drop operations as well, albeit slowly).
Since the assumption is that GOK users are using a non-core
pointing device, off-keyboard mouse clicks are current done by driving
the core mouse pointer around the desktop via specialized gok keyboard
keys. I think it would be a valuable addition to add a good Dwell
core-pointer user mode to GOK sometime in the future.
This is possible via XEvie, whereas in the past it was not technically
