palmer Construct 2 can certainly do what you want - and it doesn't get any easier than C2 from what I have seen.
C2 doesn't export swf files, but it does build HTML5 games that run in browsers.
There is a learning curve to get over, but there are lots of templates to try, tutorials to read, and a very friendly and helpful community if you get stuck. Best of all, you can try the free version to see how it all works.
