Hear, hear! zentara++. I FULLY share this opinion.

The fact that p/Tk has almost no prereqs makes it easy to build out of the box on platforms that are a nightmare to build e.g. Wx on, like AIX and HP-UX.

For me it is p/Tk all the way for ages.

As a side note: people that complained to me that Tk looked ugly quite often said they'd port my tool/app to Wx or whatever, but I have never seen any result. And when one disables decoration, p/Tk apps just look like any other app :)
