It's understandable to want flowers asap but from a good gardening point of view you don't really want those new plants to put energy into blossoming until they have built up a good strong root system. It is sensible to remove any flower buds which do form until the plant has reached a reasonable size, has a strong root system and a good branching structure (not just multiple leaves). This can be achieved by pinching out.

Well floral, you really said just what I was going to! ;) I've done several geranium cuttings, and if you have several new leaves, you should see some tiny buds before to long. =)
