GUI builder Python for Linux and OSX
<p>I just want something that is easiest to use for building a relatively simple GUI that
ports easily to OSX and Ubuntu Linux. </p>

<p>More than anything, I just want to get cracking on the App rather than getting caught up in
making something super polished, etc. </p>

<p>GLADE comes up a lot but doesn't strike me as the easiest, though, if someone suggests otherwise I'm open. </p>

<p>Again, main criteria is ease of use and portability to OSX and Linux. </p>
