Well, I hope you will take a serious look at it as a technology stack worth learning, because when you get things rigged up so that you can really just push your changes into a repo and get the builds for all platforms, its some kind of magic, and you will - most likely - be really inspired to create something great.

Which, I hope, you do.

(PS; - the default UI skin is, imho, intentionally a tad bland in order to promote developer uptake of JUCE' pretty amazing skinning/UIBehaviour system...)
