Does Windows allow you to have a window using the help button and the min / max buttons?

I want to put help buttons in all my windows, for example:

enter image description here

But when I click the help button, the minimize / maximize buttons will disappear. Does Windows prohibit having min / max buttons along with help buttons? This would be disappointing, because it would mean that I can put the help button only on dialogs, not on frames.

If Windows prohibits this, it would be nice to see a Microsoft white paper that talks about this policy.
