Compiling any of the coin daemons GUI is not as difficult as it might seem:
First make sure you have these 5 dependencies installed:
You can use apt-get install, aptitude search or aptitude install for Ubuntu and distros based on it, and for most other distros. For others you may need to use RPM or YUM but they all work very similar.
build-essential
libdb++-dev
libboost-all-dev
libleveldb-dev
libssl-dev
To make QT versions use QT creator. Search and install it they same way or use your disto's software center.
After QT creator is installed you will have it as a menu item, usually under development.
Open QT creator and click file - Open file or project. Navigate and select the bitcoin-qt.pro file in the Bytecoin or which ever coin .pro file your want to compile.
A couple of smaller windows will open if you never opened that .pro file before, just click configure and Qt creator will start chugging away.
After it configures it will start parsing the file, you can see a little grey progress bar above the computer icon 3/4 the way down.
When it is done with that, the hammer icon on the lower left will go from grey to color, just click that icon and creator will start compiling. If you want to watch it compile just click the Compile Output button on the lower right.
That it, when it is done , you should have a new folder in your home directory, along the lines of bitcoin.qt build......
In that directory you will find the new QT executable for the coin.
This is a much safer route then blinding downloading a pre-compiled binary from some non official source.
