Its possible to lead just about any type of event you wish to host. In wvw for example you will need to lead a few lower level objectives and claim leadership for them before you will be able to claim leadership for higher level objectives. Just about anyone can lead attacks on supply camps, and ally camps for example. After youhave claimed leadership for a few of these you will be able to lead against towers, after a few of these its on to keeps, and then after a few of them then you can claim objectives such as stonemist castle. PVE has similar limitations, start low and build up to leading zone wide events.
Start small and work your way up. You will have more fun, and so will the people running with you. No one learns to excell at anything without practice and by starting out slow! You will get there faster than you may imagine.
