My buddies and I want to build an RF transmitter to energize RFID tags. This tags works in a frequency range of 900- 926 Mhz. We have no Idea where to start. Would you please help us?

Search IC manufacturers for RFID datasheets and demo boards
This is a pretty vague request. Do you mean you want to read them? There are bunches of different types of tags, including read/write tags and rfid tags that output sensor data, such as max/min temp or shock for shipped goods.
What I did when I was researching RFID tags was to search for it on the internet. I bounced around until I found the IC manufacturers and then got general information, selection guides, data sheets and application notes. It's likely that the data sheets will have schematics for the tag readers. They may even have demo boards with simple computer interfaces. The demo boards are often cheap and the demo board documentation generally includes schematics and parts lists, if you want to build your own. You can't do much better than that.
Try all the IC manufacturers you can find. Some have way better documentation.
If also find using a mouse difficult which from what I notice , that you can post a question so I’m rather under the assumption that you can you use a mouse but just in case you cant, fear not , as here is just for people like yourselves a very exceptional program which will help train people in the use of a mouse
Hopefully after completing these exorcises you should then be able to perform a search all on your own
Isn' t that fantastic now how helpfull can people possibly be " Blimey i just dont know anymore !! No wonder Im losing my hair "
