Congratulations and good luck!

This is probably a good idea for now as trying to coerce qmake into
building libpurple is kind of redundant. We already have a build
system that works. At some point, it was even on the table that we'd
split libpurple/Finch/Pidgin into separate releases, but we haven't
had any great reason to do so so far. There's definitely no reason to
keep another UI in the tree, especially given its relatively young

There are advantages and disadvantages of using either one.
The stable 2.x.y branch is:
- Stable, naturally. No real need to worry about any problems building
once you first get it working.
- Already packaged. Assuming you are on Linux, then you can set up
qmake to use your distro's files. You don't even need to mess with
building libpurple. You might be able to do the same thing on Windows
(ask Eion or Tomasz).
The 3.0.0 branch is:
- Not totally stable. If you need to change things, you can do see
easily. The only thing that comes to mind is the event loop. If Qt and
GTK's loops are sufficiently different, we might need to throw
something into the libpurple API.
- Mostly stable. Yes, this is contrary to the previous point, but it
seems like much of the libpurple API changes have already been made.
The only major thing left is GObjectification, but we can't have you
waiting till the end of GSoC for that, so it's not really important
for our purposes.
My gut feeling is to stay with 2.x.y unless absolutely necessary. The
most likely changes are in the event loop, so I would focus on
determining any issues there. You do not really need to worry about
webkit. That's almost entirely in the Pidgin UI. There might be some
small changes in the format of the actual message content, but I don't
think you'll face any issues due to it. In fact, you are free to start
using QtWebkit from the beginning (just as InstantBird used xulrunner
and not GtkIMHtml).
