Solo mining by wallet is really not good idea with current hashrate and difficulty.
If You need help setting up miner go to http://forum.berncoin.org/index.php and ask Steve he will help You for sure
You need the minerd.exe executable in the same directory as the Qt wallet. If you want to use a different executable, such as this, you would need to rename the appropriate executable to "minerd.exe" so the in-wallet mining can issue commands to it. After that, simply fill out your pool information in the mining tab and press start mining.
Yes, it can and is being upgraded to "easy mode". In fact, "very easy mode". It presently is in the works friend!
Thank you for your interest in mining the BERN! If you are in need of further assistance, I would be glad to help.
