勉強{べんきょう}する is one verb. 勉強をする is a phrase.

They don't seem to have any difference in meaning, but the usage may differ.

For 勉強する, an objective can be added:

日本語{にほんご}を勉強する learn Japanese
日本語を勉強をする is wrong

For 勉強をする, adjectives (or words or phrases that can be used as adjectives) can be used before 勉強:

しばらく医者{いしゃ}になるための勉強をする study for a while to become a doctor

While 勉強する cannot be used in this way.

So could you say 日本語の勉強をする? – atlantiza Dec 15 '11 at 18:07
@atlantiza Yes. That would be more straightforwardly contrasted with 日本語を勉強する. – user458 Dec 15 '11 at 21:16
@fefe: Thanks for explanation. – Mudassir Dec 16 '11 at 4:24
