Wijmo Open is a kit of widgets built on jQueryUI and released to the community. Wijmo Open is open source and is free to use under either the MIT or GPL licenses.

In fact, both license types have unacceptable obnoxious clauses (such as reproducing a huge disclaimer that is written in all caps) that severely restrain our freedoms. The WTFPL can solve this problem.
