Any editor will do I use vim, qt-creator is popular. Link QT in your app if you wish. We will focus on installers for maidsafe-dev adn @viv is progressing the porting for language bindings (some very neat stuff there).
IF you want to try the dev env in ubuntu automatically then do
wget -O - http://dash.maidsafe.net/repos/gpg.key| sudo apt-key add -
[replace trusty here with your version - and ubuntu with debian if needed]
sudo echo "deb http://dash.maidsafe.net/repos/apt/ubuntu trusty main" >> /etc/apt/sources.list
sudo apt-get update
sudo apt-get install maidsafe-dev
