Hi
as far as I know, gmsh is an unstructured mesh generator, so by default
that generates triangular meshes(in 2D). By 'transfinite' definition
triangles are combined into quads(I hope this is not wrong, anyway
developers will comment on that.)

There should be transfinite examples to generate quad meshes in the
tutorials. Mesh order could be set with the options, I have used this
before but do not remember now, sth like secondOrder complete, you can
set that to 1 or 0 depending on the choice, that should be in the manual.
