To be honest, I stopped playing with Pharo around the time when Spec was being designed and beta-tested - I forgot most of it, but I hazily recall that it was a bit too magical for my taste. I hope it got better since then, but I'd have to check.

But, about the GUI, I was thinking about Morphic. It's basically a GUI designer on its own: you can create widgets by instantiating their objects in Playground. It doesn't matter what widget it is: you can create a button or a list item or a textarea on their own. You can then edit them with halo actions or in the inspector until they look like you want, then add them to container widgets, then finally put them in a window. It's bottom-up programming for GUIs! You need to manually track the changes you make via inspector (ie. to copy them to playground), but if you do, you can copy the whole playground into a method and done, you've just designed a GUI app! You later replace some Widgets with their subclasses written by you to handle events and you're done.

I didn't know you could do that. Any chance there is a video on YouTube showing how to do it?

Unfortunately, no, I don't recall anything like this. Executing something like `b := ButtonMorph new openInHand` in the playground would be a start - you can then set click action and caption on `b` and changes should be reflected immediately in the world. Take a look at Morph subclasses and try instantiating ones that seem interesting. Or Alt-Shift-click any widget on the screen to invoke its halo - it will display its class name, and also there's a "duplicate" button in the halo. It's quite discoverable if you put in the effort, although yeah, I'd kill for a good summary and overview of all the various widget kinds and ways of composing them...
