[racket] Can I make the frame% instances transparent?

These days I am researching on a new Editor/IDE to take the place of Vim
and Emacs.
In order to learn programing languages(not only racket) deeply I won't make
it as the DrRacket's plugin.

I also like the transparent style in which way I use terminal so that I can
check resources at the same time when coding. Is there any direct way to
get it?

Racket provides lots of graphic documents, but I think they are not good
organised. Do (big-bang) and the HtDP teachpacks suitable to build real
world GUI applications?

Thanks in advance.
