sure it can (as does any markup). not sure what this has to do with an asp.net page.
GWT applications are written in java, and compiled to javascript. singular adds the angularJS framework to GWT. that is, you still code in java, the compile output uses the angularJS framework.
not sure why you would want to use GWT rather than vanilla angularJS with todays modern javascript tools. google appears to be moving to Typescript/angularJS over GWT anyway.
with the current trend in javascript for functional coding over inheritance (class), not even sure TypeScript has a future.
