Is it possible to use the Flex Framework and Components, without using MXML? I know ActionScript pretty decently, and don't feel like messing around with some new XML language just to get some simple UI in there. Can anyone provide an example consisting of an .as file which can be compiled (ideally via FlashDevelop, though just telling how to do it with the Flex SDK is ok too) and uses the Flex Framework? For example, just showing a Flex button that pops open an Alert would be perfect.
If it's not possible, can someone provide a minimal MXML file which will bootstrap a custom AS class which then has access to the Flex SDK?
