the only restriction is time, so I still advise flex, it is a proved technology 1) best argument for flex is why people use flex over pure as3 qooxdoo have many good things, but it is like coding in pur actionscript 3 flex is a markup language, you do youre UI in declarative way 2) tooling for flex u can use flashdevelop with flexsdk and u can do ur UI in flash builder using designer mode 3) no easy skinning for qooxdoo, please prove me wrong
