Windows CE on SB1?

My company is investigating purchasing several SB1 units (for warehouse inventory/tracking/etc), and I am an in-house developer. I am researching to make sure I can write the needed software for it.

I have seen references to a Windows CE API, but the only actual tutorials I have found are for HTML single page apps (and they are several years old). Is there a Win CE API? If so, can someone point me to documentation/resources?
