If you like Delphi but want something newer than v5 and you want it for free, you could try the Turbo Delphi Explorer
Of course you are not going to be able to just drag & drop and have magical custom shaped GUI's. You are going to have to learn how to code them.
I have done some interesting image based GUI stuff in Delphi, coding all the stuff for the buttons & everything myself, in Delphi 6.
Attached is a demo of what I did (buttons don't actually do anything, but it does display how they look when clicked). Eventually, when I finish what I want to do with it (might not be for a long time), I plan on releasing it as a set of components, but don't hold your breath waiting on that.
