Er, no there isn't.
"Bills" are debt instruments which, when issued, have a maturity of less than with less that 1 year / 18 months. They are normally issued at a discount to redemption value and pay no coupon ie they are issued at the net present value of 100 in (say) 1 years time. Thus thy may be considered to be zero-coupon bonds (you may also model them as bonds with a long first coupon payment but that will f**k up your asset swap spreads). They are generally issud to manage "short term" monetary flows.
"Bonds" generally pay a coupon annually (dollar & euro bonds) or semi-annually (sterling & ex-commonwealth) and can have maturities out to 50 years.
Variations on a theme would, for example be FRN's (Floating Rate Notes) whose coupon gets reset every three months against the current 3 month libor/euribor (whatever) rate, inflation bonds whose where the coupon is inflation + a small amount, callable bonds, amortising bonds etc etc etc
There is no differencer at all "between money created by the government in the form of bills, and that produced by bank loan (of which government bonds are a form)" and indeed, Govvie bonds are not a form of bank loan (actually they are the exact reverse)
A bond/bill is simply an IOU. The coupon (interest paid) or discount price depends on the credit rating of the issuer (Government or Corporate) vis a vis the risk free rate at maturity of the redemption currency.
Any further questions please don't hesitate etc.
