It doesn't look like the skills learnt in creating a flex app, translate very well to HTML
you have to rethink, redesign the thing?

Yes, and I confirm it's very painful.
A second challenge is to keep your code cross-browser. You have to keep in mind it can be run on different browsers that may interpret your code differently. Flex-apps run in a flash player, that's all.
Ajax is fairly ok. I got in touch with it to assynchronously load external data and I haven't run into any major difficulties.
To conclude, I would say HTML+Ajax is a good option if your solution remains pretty basic, but as you embed media, animations, etc,... things will become much more complex to a point where I think it's better to work out a solution in Flex.
