Strictly speaking, if God were an immaterial being, then she would not need any material to start with. Also classical theism regard's God's Being as eternal and changeless, and also not compounded (made of individual elements or parts).
However, the objection you raise is a valid one, though more so along these lines:
1) The idea or concept of existence, when predicated on God, does not add existence to God, nor does it prove she exists (Hume and Kant pointed out the flaws in this argument, as did Guanlino, Anselm's opponent)
2) The idea of a first cause does not need to end necessarily with God. The world could have been made by several intelligent beings as an experiment or even a cruel joke (as Hume points out in Dialogues on Natural Religion) or simply have come into being on its own accord (as several modern cosmological theories suggest).
Occam's razor is also useful to consider as well.
