```*Dear Steve,

Subscript[q, #] & /@ Range

Seems simple to me!
Further if you wanted to generate a matrix,

Table[Subscript[q, i, j], {i, 1, 3}, {j, 1, 4}] gives

{{Subscript[q, 1, 1], Subscript[q, 1, 2], Subscript[q, 1, 3],
Subscript[q, 1, 4]}, {Subscript[q, 2, 1], Subscript[q, 2, 2],
Subscript[q, 2, 3], Subscript[q, 2, 4]}, {Subscript[q, 3, 1],
Subscript[q, 3, 2], Subscript[q, 3, 3], Subscript[q, 3, 4]}}
