Yes you can.

You just left click blocks. You can only get things like dirt and logs with your hands. You need to make a wooden pickaxe to mine stone and coal, to mine iron you need a stone pickaxe, to mine diamonds and redstone you need a iron pickaxe, and to mine obsidian you need a diamond pickaxe. Each type of pickaxe and break the blocks that lower level picks can mine (like iron picks can break all the blocks that stone blocks can break). Shovels and axes just break their respective blocks faster(axe mines wood faster, shovel mines dirt/sand faster).
To place blocks in minecraft, right click. To destroy them, left click.
You shift click on the block and place it where you want it
Redstone blocks? You need an iron pickaxe.
