Beginners do lift that, I see it every day in my gyms. They do a half-rep, the bar doesn't touch their chest, and their squat, deadlift, and other lifts are much, much less than that.
One of the signs of being a complete novice is that your bench press is higher than your squat or deadlift, and the squat and deadlift are under your bodyweight. As Markos said, nothing wrong with being a beginner. Everyone has to start somewhere.
What he said, you should listen to.
Squat. Start with empty bar. Do 5 reps. Add 5kg, and do 5 reps more. Repeat until you cannot get 5 reps. That is your starting work weight for squats.
Overhead press. Start with empty bar. Do 5 reps. Add 2.5kg, and do 5 reps more. Repeat until you cannot get 5 reps. That is your starting work weight for overhead press.
Deadlift. Start with the bar plus a 20kg plate each side. Do 5 reps. Add 10kg, and do 5 reps more. Repeat until you cannot get 5 reps. That is your starting work weight for deadlift.
Next time in the gym, your routine will be,
Squats, 5x4 warmup, 3x4-6 work weight. Add 5kg each time you progress.
Overhead press, 3x6 warmup, 3x4-6 work weight. Add 2.5kg each time you progress.
Deadlift, 3x4-6 warmup, 3x4-6 work weight. Add 5kg each time you progress.
With the warmup, begin with the empty bar (or with 60kg in deadlift) for your first set, then go up in roughly equal steps to your work weight. For example, if your working weight for squats were 60kg, you'd go - warmups 20kg 1x4, 30kg 1x4, 40kg 1x4, 50kg 1x4, 55kg 1x4, then work 60kg 3x4-6.
With the work sets, notice there's a range given. In your first session, do 3x4. In your second, 3x5. In your third, 3x6. When you can do 3x6, add the weight listed then drop back to 3x4.
If you cannot make the target reps, you owe reps with 100% interest. For example, if you were supposed to 3x6 and only managed 6,5,4, then you are short by 3 reps, so you owe 6 reps. You have to get out 6 reps, even if it's only 1,1,1,1,1,1. Don't add weight until you can get 3x6 straight across.
Eat heaps of good food. Stretch after your workout. On your off days, do some light cardio like an hour's brisk walk or half hour jog or swim, this helps your recovery, means less pain.
Keep at it, keep it simple. Consistent effort over time gets results. This is simple, not easy.
