In theory, I don't know, but in practice it is possible ;-).
Look at GWindows for instance.
And I'm sure (hum, why am I so sure ?...) that CLAW as well is a GUI
library without need of accesses.
At least on GWindows the only need I've seen, up to now, for accesses
is when it comes to create an undetermined number of MDI windows (e.g.
in the TeXCAD app).
